The invention solves the problem that the corresponding heating power and the water flow rate are required to be obtained again through an algorithm when a user sets the temperature and fetches water each time in the prior art, and achieves the technical effects of improving the water temperature control efficiency, shortening the water outlet response time, reducing the waiting time of the user and improving the use experience.

Example one

Referring to fig. 1, which is a schematic flow chart of a method for controlling a water temperature of an instant heating type water dispenser according to a first embodiment of the present invention, for convenience of description, only parts related to the embodiment of the present invention are shown, and the method for controlling the water temperature of the instant heating type water dispenser includes:

step S10, acquiring a target water temperature set by a user;

in the embodiment of the invention, the instant heating type water dispenser water temperature control method is applied to an instant heating type water dispenser, a user can set the target water temperature through interaction with the instant heating type water dispenser and also can set the target water temperature through interaction with an equipment terminal, the equipment terminal can be an intelligent terminal, an intelligent panel, an intelligent home terminal and the like, an application program is installed on the equipment terminal, and the application program of the equipment terminal can be communicated with a cloud server of the instant heating type water dispenser.

Step S20, judging whether the target water temperature is stored;

step S30, if not, determining corresponding water temperature control parameters according to the target water temperature;

step S40, if yes, reading the target water temperature and determining a corresponding water temperature control parameter;

step S50, controlling the water dispenser to process the water body to the target water temperature according to the water temperature control parameter corresponding to the target water temperature, and sending a water outlet instruction;

In the embodiment of the invention, after the target water temperature set by a user is obtained, the energy required for reaching the target water temperature is obtained through calculation, and the optimal heating power parameter and water flow velocity parameter are determined according to the required energy. The heating power parameter and the water flow rate parameter can be obtained by calculation through a constant water temperature control algorithm, such as a PID algorithm, and according to the energy required for reaching the target water temperature, the fixed heating power parameter can be selected and only the water flow rate parameter is adjusted; or, fixing the flow speed parameter of the water body and only adjusting the heating power parameter; or, the heating power parameter and the water flow speed parameter are adjusted simultaneously. And after the heating power parameter and the water body flow velocity parameter are determined, establishing a corresponding relation between the parameters and the target water temperature, and storing the parameters.

When the instant heating type water dispenser is used for the first time, the default target water temperature is the water temperature (generally normal temperature or room temperature) of drinking water, and a user also sets other target water temperatures through interaction with the instant heating type water dispenser. And (4) for the first time, namely the target water temperature parameter is not stored, controlling and confirming the water temperature control parameter according to the target water temperature heating algorithm, and discharging water after the target water temperature is reached.

According to the foregoing description, it can be understood that if the water dispenser is used for the first time, the user does not set other target water temperatures to directly operate the outlet water, the water temperature of the drinking water is consistent with the target water temperature, and the energy required for reaching the target water temperature is zero, the heating power parameter and the water flow rate parameter do not need to be controlled and adjusted, that is, the target water temperature does not have the corresponding heating power parameter and water flow rate parameter, and the target water temperature does not need to be stored.

As can be understood from the foregoing description, if the user directly operates the effluent without setting the target water temperature, the water body does not need to be treated.

In research and development, the inventor verifies through tests that the water temperature control method provided by the embodiment of the invention can greatly improve the water temperature control efficiency and shorten the water outlet response time, and the test data records are shown in table 1.

Table 1: water outlet time test data recording table

Need to explain: in table 1, the test condition "normal temperature to 40 ℃" represents that the drinking water is heated from normal temperature to 40 ℃, and the description is also omitted;

the test item 'first heating' represents that a user uses the water temperature control parameter for the first time, and at the moment, the water temperature control parameter is not stored, and the corresponding water temperature control parameter needs to be obtained according to the target water temperature.

In the existing instant heating type water dispenser, a user heats and takes drinking water each time, the water dispenser adopts a control algorithm to adjust a water temperature control parameter, and then the water dispenser is controlled according to the parameter to treat water to a target water temperature set by the user and then discharge water, the process is similar to the first heating in a test project, and the water discharge response time is approximately equal to the water discharge response time of the first heating minus 5s for preventing dry-burning waiting. By taking the water temperature as a reference, the test data records show that the water temperature control method provided by the embodiment of the invention can greatly prolong the water response time.

In the embodiment of the invention, when the water heater is used for the first time, a better heating power parameter and a better water flow velocity parameter which reach the target water temperature are obtained through an algorithm, and a corresponding relation is established for storage; and then, in each use, whether the target water temperature used at this time is stored is judged firstly, if yes, the corresponding heating power parameter and the water body flow velocity parameter can be read only according to the target water temperature, the time consumption on the parameter is not needed to be calculated, the calculation power distribution is optimized, and the time from the time that a user sets the target water temperature to the time that the instant heating type water dispenser responds to water outlet is further shortened.

In the embodiment, when the water heater is used for the first time, the target water temperature set by a user is obtained, the corresponding heating power parameter and the corresponding water body flow velocity parameter are determined according to the target water temperature and are stored, and then the water heater can be used for each time; if the target water temperature set by the user is the target water temperature set for the first time, the establishment of the corresponding relation between the target water temperature and the heating power parameter and the water body flow velocity parameter is completed firstly, and the target water temperature is stored for later use and is read. The embodiment of the invention solves the problem that the corresponding heating power and the water flow rate are required to be obtained again through the algorithm when a user sets the temperature and fetches water each time in the prior art, and achieves the technical effects of improving the water temperature control efficiency, shortening the water output response time, reducing the waiting time of the user and improving the use experience.

Example two

Referring to fig. 2, the second embodiment of the present invention has a flow substantially the same as the first embodiment, and for the sake of brief description, reference may be made to corresponding contents in the first embodiment, where the step of determining the corresponding water temperature control parameter according to the target water temperature further includes:

step S31, presetting a plurality of water temperature difference intervals, and heating power parameters and water flow rate parameters which are in one-to-one correspondence with the water temperature difference intervals;

in the embodiment of the invention, the energy required for reaching the target water temperature is obtained through calculation, and the required energy is reflected by the difference between the target water temperature and the real-time water temperature. The inventor finds that in the practical use of the instant water dispenser, when the difference between the target water temperature and the real-time water temperature is within a certain interval, the time difference required for processing the water body to the target water temperature is extremely small, and the influence on the use experience is extremely small, so that the same heating power parameter and the same water body flow velocity parameter can be adopted within a certain water temperature difference interval.

Step S32, acquiring real-time water temperature; calculating to obtain a water temperature difference value between the real-time water temperature and the target water temperature; judging a water temperature difference value interval in which the water temperature difference value falls;

the real-time water temperature can be obtained by a temperature detection device arranged in the instant water dispenser, such as a temperature sensor, and is compared with a target water temperature to calculate a water temperature difference value, and the water temperature difference value can be limited to an absolute value, namely a numerical value greater than zero, through a calculation formula according to the requirement of dividing a preset water temperature difference value interval; values less than zero may also be included. After the water temperature difference is obtained through calculation, the water temperature difference is respectively compared with each preset water temperature difference interval, and then the water temperature difference interval in which the water temperature difference falls can be judged.

And step S33, determining corresponding heating power parameters and water flow rate parameters according to the water temperature difference interval.

The instant heating type water dispenser water temperature control method provided by the embodiment of the invention is characterized in that a plurality of water temperature difference intervals, heating power parameters and water body flow rate parameters which are in one-to-one correspondence with the water temperature difference intervals are preset, real-time water temperature is obtained and is compared with target water temperature set by a user, a water temperature difference is calculated, and after the interval in which the water temperature difference falls is judged, the corresponding heating power parameters and water body flow rate parameters can be determined, so that the algorithm is simplified, calculation power distribution is optimized, response time is shortened, meanwhile, the true and effective heating power parameters and water body flow rate parameters can still be ensured to be obtained, and the same heating power parameters and water body flow rate parameters are adopted in a certain water temperature difference interval, so that the water temperature control method is more in line with the actual use condition of the instant heating type water dispenser, the complexity of user operation can be reduced, and the learning and use time of the user can be saved, leading to a better use experience.

EXAMPLE III

Referring to fig. 3, the third embodiment of the present invention has a substantially same flow as the first and second embodiments, and for brief description, the embodiment of the present invention is not mentioned, and reference may be made to the corresponding contents in the first and second embodiments, in the method for controlling a water temperature of an instant heating type water dispenser, the step of presetting a plurality of water temperature difference intervals, and the heating power parameters and the water flow rate parameters corresponding to the plurality of water temperature difference intervals one to one further includes:

step S311, presetting heating power slopes k corresponding to a plurality of water temperature difference intervals one by one ₁ By the formula P ═ P _t k ₁ Determining heating power parameters corresponding to the water temperature difference interval, wherein P represents the heating power parameters, and P represents the heating power parameters _t Represents the rated heating power;

it is understood that P represents a heating power parameter, i.e. a finally determined heating power parameter, P _t The representative rated heating power refers to the maximum power which can be provided by the instant heating type water dispenser when the instant heating type water dispenser is continuously heated, and further, the heating power slope k ₁ Is a scaling parameter not greater than 1.

In the embodiment of the invention, the finally determined heating power parameter is obtained by multiplying the rated heating power and the heating power slope, wherein the rated heating power is a fixed constant, and only the heating power slope is a unique variable in the calculation formula, so that the unique variable can be converted into the water temperature difference range by presetting the heating power slopes corresponding to a plurality of water temperature difference ranges one by one, and further converted into the water temperature difference.

Step S312, presetting water flow velocity slopes k corresponding to a plurality of water temperature difference intervals one by one ₂ By the formula V ═ V _t -k ₂ C, determining water flow velocity parameters corresponding to the water temperature difference value intervals, wherein V represents the water flow velocity parameters, and V _t Representing the real-time water flow rate, and C representing the water flow rate constant.

It can be understood that the water flow velocity parameter represented by V is the finally determined water flow velocity parameter, V _t The representative real-time water flow rate refers to the initial water flow rate of the instant heating type water dispenser starting to process the water body when a user sets a target water temperature and operates the water outlet, the initial water flow rate is related to the duty ratio of the water pump, and the duty ratio of the water pump and the water flow rate can be linearly relatedNamely, the duty ratio of the water pump is increased, and the flow velocity of the water body is synchronously increased; the duty ratio of the water pump is reduced, and the flow velocity of the water body is synchronously reduced; the water flow rate constant represented by C can be adjusted according to actual conditions, and in the embodiment of the invention, the water flow rate constant is a positive number greater than zero; further, the water flow rate constant C and the water flow rate slope k ₂ The product of (a) is the variation of the flow velocity, and the flow velocity can be increased or decreased or maintained as required, so that the slope k of the flow velocity of the water body ₂ And may be any rational number.

In the embodiment of the invention, the finally determined water flow velocity parameter is obtained by controlling the increase and decrease of the flow velocity variation quantity on the basis of the initial water flow velocity of the water body processed by the instant water dispenser, wherein the variable can be converted into the water temperature difference interval by presetting the water flow velocity slope corresponding to a plurality of water temperature difference intervals one by one, and further converted into the water temperature difference. For example, when the difference between the real-time water temperature and the target water temperature set by the user is large, the energy required for reaching the target water temperature is also large, in order to ensure rapid heating, the heating power parameter can be fixed at the maximum rated power in a control period, at this time, the water temperature can be controlled by controlling the water flow rate parameter, specifically, the falling water temperature difference interval corresponds to a large water flow rate slope, a large flow rate variation is subtracted on the basis of the initial water flow rate, so that the water flow rate parameter is reduced, the water pump duty ratio is reduced, that is, the time of the water staying in the heating area is prolonged, and the water temperature is rapidly increased. Therefore, the calculation is simpler and more convenient, and the time consumption is shortened.

For example, the heating power gradient k corresponding to a plurality of water temperature difference intervals ₁ The method specifically comprises the following steps:

the water temperature difference is more than or equal to 40 ℃, k ₂ ＝1；

40℃>The water temperature difference is more than or equal to 30 ℃, k ₂ ＝0.88；

30℃>The water temperature difference is more than or equal to 10 ℃, k ₂ ＝0.5；

10℃>The water temperature difference is more than or equal to 0 ℃, k ₂ ＝0；

0℃>The water temperature difference is more than or equal to-4 ℃, k ₂ ＝0.1；

-4℃>The water temperature difference is more than or equal to-10 ℃, k ₂ ＝0.05；

In the embodiment of the invention, when the difference value between the real-time water temperature and the target water temperature set by the user is larger, the energy required for reaching the target water temperature is also larger, and in order to ensure the heating efficiency, a larger heating power slope is correspondingly preset, so that a larger heating power parameter can be obtained at the moment; otherwise, a smaller heating power slope is preset correspondingly.

Water body flow velocity slope k corresponding to a plurality of water temperature difference intervals one by one ₂ The method specifically comprises the following steps:

the water temperature difference is more than or equal to 40 ℃, k ₁ ＝10；

40℃>The water temperature difference is more than or equal to 30 ℃, k ₁ ＝8；

30℃>The water temperature difference is more than or equal to 10 ℃, k ₁ ＝5；

10℃>The water temperature difference is more than or equal to 0 ℃, k ₁ ＝0；

0℃>The water temperature difference is more than or equal to-4 ℃, k ₁ ＝-2；

And the water temperature difference value is the difference between the target water temperature and the real-time water temperature.

In the embodiment of the invention, when the difference value between the real-time water temperature and the target water temperature set by the user is larger, the energy required for reaching the target water temperature is also larger, and in order to ensure that the energy is fully converted into the heat of the water body, the stay time of the water body in the heating area needs to be prolonged, so that a larger water body flow velocity slope is correspondingly preset, and a smaller water body flow velocity parameter can be obtained at the moment; otherwise, a smaller preset water body flow velocity slope is correspondingly set.

The heating power parameter and the water flow rate parameter are determined according to the actual requirement, and the determination can be carried out synchronously.

Specifically, for example, the rated power of the instant heating type water dispenser is 2000W, and target water set by a userThe temperature is 95 ℃, the obtained real-time water temperature is 25 ℃, the water temperature difference value is calculated to be 70 ℃, the water temperature difference value falls into an interval of 'the water temperature difference value is more than or equal to 40 ℃', and the heating power slope k is correspondingly obtained ₁ The value is 1, and then a heating power parameter which is equal to the maximum rated power and is 2000W is obtained by calculation according to a formula; correspondingly obtaining the flow velocity slope k of the water body ₂ And the real-time water flow rate is obtained to be 0.5L/min and the water flow rate constant is obtained to be 0.02 at the moment, and the water flow rate parameter is calculated to be 0.3L/min according to a formula. And establishing a corresponding relation between the calculated heating power parameter 2000W and the calculated water flow rate parameter 0.3L/min and the target water temperature of 95 ℃, and when the water heater is used for each time, firstly judging whether the target water temperature set by a user is 95 ℃, if so, directly reading the corresponding heating power parameter 2000W and the corresponding water flow rate parameter 0.3L/min, and processing the water body according to the parameters. In the embodiment of the invention, the heating power parameter and the water flow velocity parameter corresponding to the target water temperature do not need to be obtained by recalculation in each use, so that the water temperature control efficiency is improved, the water outlet response time is shortened, the waiting time of a user is reduced, and the use experience is improved.

Example four

normal temperature, 40 ℃ is higher than the water temperature is more than or equal to 10 ℃;

the medium temperature is higher than 85 ℃ and the water temperature is more than or equal to 40 ℃;

high temperature grade, water temperature is more than or equal to 85 ℃.

In research and development, the inventor finds that in the practical use of the instant water dispenser, for drinking water with a small difference in water temperature, the perception and distinguishing capability of a user is weak, for example, drinking water at 45 ℃ and drinking water at 55 ℃ have the same mouthfeel and application for the user. Therefore, from the use experience of a user, the target water temperature can be divided into 3 gears for the user to select; wherein, the normal temperature grade is higher than 40 ℃ and the water temperature is more than or equal to 10 ℃, so that the method is suitable for users needing moderate mouthfeel; the medium temperature grade, the temperature of 85 ℃ is more than or equal to 40 ℃, and the method is suitable for users needing warm mouthfeel; the high temperature is higher than or equal to 85 ℃, and the method is suitable for brewing tea or beverage solvents.

In the embodiment of the invention, the names of the target water temperature gears are only schematic, and do not affect the actual protection range of the corresponding target water temperature, so that the target water temperature gears can be distinguished as long as the target water temperature meets the corresponding data range.

In the embodiment of the invention, the target water temperature is divided into a plurality of gears for the user to select, so that the actual use scene is better met, the user operation is simplified, the learning use time is saved, and the use experience is improved.

0℃>The water temperature difference is not less than-4℃，k ₁ ＝-2；

Specifically, for example, the rated power of the instant heating type water dispenser is 2000W, the target water temperature set by the user is 95 ℃, the acquired real-time water temperature is 25 ℃, the calculated water temperature difference is 70 ℃, the obtained water temperature difference falls into an interval of' the water temperature difference is not less than 40 ℃, the heating power slope k1 is correspondingly obtained to be 1, and then the heating power parameter which is equal to the maximum rated power and is 2000W is obtained by calculation according to a formula; and correspondingly obtaining the water flow rate slope k2 of 10, obtaining the real-time water flow rate of 0.5L/min and the water flow rate constant of 0.02 at the moment, and calculating according to a formula to obtain the water flow rate parameter of 0.3L/min. And establishing a corresponding relation between the calculated heating power parameter 2000W and the calculated water flow rate parameter 0.3L/min and the target water temperature of 95 ℃, and when the water heater is used for each time, firstly judging whether the target water temperature set by a user is 95 ℃, if so, directly reading the corresponding heating power parameter 2000W and the corresponding water flow rate parameter 0.3L/min, and processing the water body according to the parameters.

Therefore, from the use experience of a user, the target water temperature can be divided into 3 gears for the user to select; wherein the normal temperature is higher than 40 ℃ and the water temperature is more than or equal to 10 ℃, so that the method is suitable for users needing moderate mouthfeel; the medium temperature grade, 85 ℃ and the water temperature are more than or equal to 40 ℃, so that the method is suitable for users needing warm mouthfeel; the high temperature is higher than or equal to 85 ℃, and the method is suitable for brewing tea or beverage solvents.
