Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating embodiments of the invention, are given by way of illustration and explanation only, not limitation.
The traditional temperature control algorithm of the drinking water equipment is based on the standard that the temperature of the water outlet reaches a set target, but a user actually concerns whether the temperature of water in a cup is accurate or not. In real life, for example, when a user just takes a cup of water with a higher temperature, such as 90 ℃, and then takes a cup of water with a temperature of 45 ℃ for making milk, the residual water in the pipeline of the drinking device is high-temperature water with a temperature of about 90 ℃ required by the previous cup of water. In this case, the control algorithm of the conventional drinking water apparatus, such as the PID algorithm, since the water temperature at the water outlet is higher than the target temperature, will reduce the temperature of the water outlet by continuously and dynamically adjusting the driving values of the heat pipe and the water pump until the water outlet temperature is consistent with the target temperature. Under such a condition, the temperature of water in a cup filled with water is higher than a target temperature because the water initially falls into the cup, and the temperature of the water in the cup after final mixing is often higher than the target temperature.
To solve the above problems, embodiments of the present invention provide a method for a drinking water apparatus. FIG. 1 is a schematic flow chart of a method for a drinking water apparatus according to an embodiment of the present invention. As shown in fig. 1, in an embodiment of the present invention, a method for a drinking water apparatus is provided, which is described by taking a processor of the drinking water apparatus as an example, and the method may include the following steps:
and S102, acquiring the residual water temperature of the residual water remained in the drinking equipment.
Wherein, the residual water in the drinking water equipment is the water retained in the pipeline and/or the heating device of the drinking water equipment before the drinking water equipment receives the water taking instruction.
Specifically, when the processor of the water drinking device receives the water taking instruction, the processor acquires the residual water temperature of the residual water remaining in the pipeline and/or the heating device of the water drinking device when the water drinking device takes water last time, and further, the residual water temperature can be obtained through a temperature sensor or a specific algorithm.
And step S104, in the case that the residual water temperature is determined not to meet the target water intaking temperature, outputting compensation water to be mixed with the residual water.
It can be understood that the target water getting temperature is the temperature of water needed or expected by the user, and can be obtained by a water getting instruction triggered or clicked by the user, and can also obtain a pre-stored temperature default setting value, and the temperature default setting value can be the water getting temperature when the user gets water last time, or the setting temperature changed according to the difference of time, season or place where the user is located, for example, the water getting temperatures of normal temperature water gears in winter and summer are different.
Further, the condition that the residual water temperature does not meet the target water intaking temperature comprises two conditions that the residual water temperature is greater than the target water intaking temperature and the residual water temperature is less than the target water intaking temperature, so that when the residual water temperature is greater than the target water intaking temperature, the compensation water with the output temperature less than the target water intaking temperature performs temperature compensation on the residual water with higher temperature; when the temperature of the residual water is lower than the target water taking temperature, the compensation water with the output temperature higher than the target water taking temperature carries out temperature compensation on the residual water with lower temperature.
Specifically, the processor outputs the compensation water having a temperature greater than the target water intake temperature or the compensation water having a temperature less than the target water intake temperature to be mixed with the residual water when it is determined that the residual water temperature does not satisfy the target water intake temperature, thereby performing temperature compensation on the residual water remaining in the water dispensing apparatus.
And step S106, controlling the temperature of the outlet water of the water drinking equipment so as to control the temperature of the outlet water to be at the target water taking temperature.
Wherein, the outlet water temperature is the temperature of the water output by the water outlet of the drinking water equipment, namely the temperature of the water in the user cup.

The amount of the residual water is mainly influenced by the waterway structure of the drinking equipment model, and the amount of the residual water is usually a fixed value because the model of the drinking equipment is fixed, and the specific numerical value can be predetermined. It is understood that the unheated water is water that has not been heated by the heating device, such as normal temperature water or cold water, and may be taken from a water tank externally connected to the water drinking apparatus, wherein the temperature of the water entering the unheated water may be obtained by a temperature sensor that measures the temperature of the water entering the water inlet pipe.
In one embodiment, the amount is a volume, and determining the amount of unheated water based on the amount of residual water, the residual water temperature, the target water intake temperature, and the intake water temperature of the unheated water includes determining the volume of unheated water based on the following equation (1):
Figure BDA0002740961480000141
wherein, VcomVolume of unheated water, TresIs the temperature of the residual water, TtarTemperature of water taken for target, TiniThe temperature of the inlet water of unheated water, VresIs the volume of the residual water, wherein the volume of the residual water can be predetermined by the model and the structure of the drinking water device.
Specifically, the processor of the water dispensing device determines the volume of unheated water based on the volume of residual water, the residual water temperature, the target water intake temperature, and the water intake temperature of the unheated water.
In some embodiments, the amount may be a weight, and determining the amount of unheated water based on the amount of residual water, the residual water temperature, the target water intake temperature, and the intake water temperature of the unheated water includes determining the weight of the unheated water based on the following equation (2):

The amount of the residual water is mainly influenced by the waterway structure of the drinking equipment model, and the amount of the residual water is usually a fixed value because the model of the drinking equipment is fixed, and the specific numerical value can be predetermined. The heating water is water generated after a heating device of the drinking water equipment is heated, wherein the temperature of the heating water is lower than the target water taking temperature.

Wherein m iscomFor heating the mass of water, mallM is a preset water intake massresThe mass of the remaining water.
In this embodiment, the amount of the heated water is determined according to the determined preset water intake amount and the determined amount of the residual water, so that the temperature of the heated water is determined according to the amount of the heated water, and thus the accurate temperature control of the water in the cup is realized.
In step S306, the determined amount of heated water is output to be mixed with the remaining water.
Specifically, the processor can control the power of a water pump of the water drinking device so as to control the water inlet flow rate, determine the compensation time according to the determined heating water amount and the water inlet flow rate, and determine that the output heating water amount reaches the heating water amount determined in the step under the condition that the running time reaches the compensation time so as to realize the mixing with the residual water pumped out in advance, thereby obtaining the water with the target water taking temperature or the water close to the target water taking temperature.
In this embodiment, when the residual water temperature is greater than target water intaking temperature, the volume of heating water is predetermined according to the volume of predetermineeing the water intaking volume and residual water, and then the output temperature is less than the heating water of target water intaking temperature in order to mix with the residual water, reduces the influence of the higher residual water of temperature, reduces the temperature deviation of the water in the cup, realizes the accurate accuse temperature of the water in the cup.

It is understood that the preset water intake is the water output of one water output preset by the drinking water device, wherein the amount can be volume, such as 120ml, or mass, such as 120 g.
Specifically, the processor may determine the preset water intake amount of the water dispenser according to the temperature range to which the target water intake temperature belongs, wherein the preset water intake amounts corresponding to different application scenarios are different because the application scenarios of water in different temperature ranges may be different.
And step S406, determining the amount of the compensation water according to the preset water intake amount and the amount of the residual water.
It can be understood that the amount of the residual water is mainly influenced by the waterway structure of the model of the drinking water device, and since the model of the drinking water device is fixed, the amount of the residual water is usually also a fixed value, and a specific value can be determined by obtaining the pre-stored amount of the residual water, for example, 20 ml.
Specifically, the processor may determine the amount of the compensation water according to the determined preset water intake amount and the pre-stored amount of the remaining water.
In one embodiment, the amount of make-up water is the preset water draw minus the amount of residual water.
In this embodiment, the amount of the compensation water is determined according to the determined preset water intake amount and the determined amount of the residual water, so as to realize accurate temperature control, and the specific calculation formula can be referred to the above formulas (3) and (4).
In step S408, the determined amount of compensation water is output to be mixed with the remaining water.
Specifically, the processor may control power of a water pump of the water dispenser to control a water intake flow rate, determine a compensation time according to the determined amount of compensation water and the water intake flow rate, and determine that the amount of compensation water output reaches the determined amount of compensation water in the case that the operation time reaches the compensation time to achieve mixing with residual water pumped in advance, thereby obtaining water at or near a target water intake temperature.

In one embodiment, the above method further comprises the steps of: and determining the temperature of the compensation water according to the amount of the compensation water, the amount of the residual water, the target water intaking temperature and the residual water temperature.
Specifically, the processor determines the temperature of the heated compensation water based on the determined amount of compensation water, the amount of residual water, the target intake water temperature, and the residual water temperature.
In this embodiment, the temperature of the compensation water is determined, so that the power of the heating device and the power of the water pump are adjusted through control algorithms such as PID control, and water meeting the temperature of the compensation water is output, and is mixed with the residual water, so that water meeting the target water taking temperature is obtained.
In one embodiment, determining the temperature of the compensation water based on the amount of compensation water, the amount of residual water, the target water intake temperature, and the residual water temperature comprises: the temperature of the compensation water is determined according to the following equation (6):
Figure BDA0002740961480000191
wherein, TcomTo compensate for the temperature of the water, VcomTo compensate for the volume of water, VresVolume of residual water, TtarIs a target ofTemperature of water taken, TresThe temperature of the remaining water.
In this embodiment, it can be understood that when the volume (V) of the water is compensatedcom) The greater the temperature (T) of the compensation watercom) The closer to the target water intake temperature (T)tar) And, conversely, the temperature (T) of the compensation watercom) With target water intake temperature (T)tar) The larger the difference value is, the temperature of the compensation water is determined through the specific algorithm, so that the water drinking equipment is controlled to normally heat the water according to the temperature of the compensation water, and the forward compensation of the temperature of the residual water is realized.
Furthermore, different application scenes and target water taking temperature ranges can be different, and accurate temperature control can be realized by determining the specific range of the target water taking temperature and then determining the preset water taking amount according to the target water taking temperature.
In some application scenarios, when the target water intake temperature (T)tar) In the range of T1≤Ttar≤T2In which T is1、T2The water receiving amount is usually smaller at lower temperature. This situation requires the preferential water receiving amount, i.e. when the temperature range to which the target water taking temperature belongs is T1To T2In time, the processor sets the preset water intake amount to V1And determining the volume of the compensating water at the moment according to the preset water intake quantity set at the moment and the formula (3), and further determining the temperature of the compensating water at the moment according to the determined volume of the compensating water and the formula (5).
In other application scenarios, the target water intake temperature (T)tar) In the range of T3＜Ttar≤T4In which T is3、T4The temperature is higher, and the instantaneous water temperature is not required to be too high, so the water receiving quantity is preferentially controlled, namely, the temperature range of the target water taking temperature is T3To T4In time, the processor can set the preset water intake to be V2And determining the volume of the compensating water at the moment according to the preset water intake quantity set at the moment and the formula (3), and further determining the temperature of the compensating water at the moment according to the determined volume of the compensating water and the formula (5).
In one embodiment, where the temperature of the compensation water is higher than the target water intake temperature, as shown in fig. 5, in the case where it is determined that the residual water temperature does not satisfy the target water intake temperature, outputting the compensation water to be mixed with the residual water includes the steps of:
and step S502, determining that the residual water temperature is less than the target water intaking temperature.
Specifically, the processor of the drinking water equipment can analyze the water getting instruction after receiving the water getting instruction triggered by the user, acquire target water getting temperature information, and compare the residual water temperature and the target water getting temperature, so as to determine that the residual water temperature is less than the target water getting temperature expected by the user.
In step S504, the temperature of the compensation water is determined according to the target water intaking temperature.
Specifically, the processor determines the temperature of the compensation water at that time based on the temperature range to which the target intake water temperature belongs.
Further, in some application scenarios, the target water intake temperature (T)tar) In the range of T5＜Ttar≤T6In which T is5、T6At moderate temperatures, since the above-described water usage scenarios are sensitive to high temperature water, if the compensation water temperature exceeds the target water temperature too high, the nutritional value of the beverage itself may be destroyed. The above-described water usage scenario therefore preferentially controls the temperature of the compensation water.
In one embodiment, the temperature of the compensation water is the target water intake temperature plus a positive offset value.
It will be appreciated that the positive offset value is a preset maximum allowable temperature offset, which may be set by a user or by default to the system, for example, 10 ℃.
Specifically, when the target intake water temperature (T)tar) In the range of T5＜Ttar≤T6When the temperature of the compensation water at this time is the target intake water temperature plus a positive offset value, for example, when the target intake water temperature is 60 ℃ and the positive offset value is 10 ℃, the temperature (T) of the compensation water at this time is determinedcom) The value of (b) is 60 ℃ +10 ℃ + 70 ℃.
In step S506, the amount of the compensation water is determined according to the temperature of the compensation water, the amount of the residual water, the target water intake temperature and the residual water temperature.
Specifically, the processor determines the heated amount of compensation water based on the determined temperature of compensation water, the amount of residual water, the target intake water temperature, and the residual water temperature.
In one embodiment, determining the amount of compensation water based on the temperature of the compensation water, the amount of residual water, the target water intake temperature, and the residual water temperature comprises: the amount of make-up water is determined according to the following equation (7):

wherein, VcomTo compensate for the volume of water, VresVolume of residual water, TtarTemperature of water taken for target, TresIs the temperature of the residual water, TcomTo compensate for the temperature of the water.
In step S508, the determined amount of compensation water is output to be mixed with the remaining water.
Specifically, the processor may control power of a water pump of the water dispenser to control a water intake flow rate, determine a compensation time according to the determined amount of compensation water and the water intake flow rate, and determine that the amount of compensation water output reaches the determined amount of compensation water in the case that the operation time reaches the compensation time to achieve mixing with residual water pumped in advance, thereby obtaining water at or near a target water intake temperature.
In this embodiment, under the condition that the temperature of the residual water is lower than the target water intaking temperature, the temperature of the compensation water is determined according to the temperature range to which the target water intaking temperature belongs, and then the amount of the compensation water is determined according to the temperature of the compensation water, so that the compensation water with the determined amount and the temperature higher than the target water intaking temperature is output according to the determined amount of the compensation water to be mixed with the residual water, and the temperature error of the actually obtained water is reduced, so that accurate temperature control is realized.
In some application scenarios, the temperature of the compensation water calculated according to the formula (6) is high, the drinking water equipment cannot be realized, and secondary compensation is required, wherein the secondary compensation is a process of performing temperature compensation on the residual water according to the corrected temperature of the compensation water.
In one embodiment, in case that the temperature of the compensation water is greater than the maximum compensation water temperature or greater than the maximum outlet water temperature, the temperature of the compensation water is corrected to a smaller one of the maximum compensation water temperature and the maximum outlet water temperature; the amount of make-up water is determined according to the following equation (8):

As can be appreciated, the maximum compensated water temperature
Figure BDA0002740961480000221
The highest water flow temperature which can be output for the full-power operation of the machine meets the following formula (9):
Figure BDA0002740961480000222
wherein,
Figure BDA0002740961480000223
to compensate for the highest water temperature, TiniFor inlet water temperature, Δ TmaxThe temperature of water flow flowing through the heating device is raised under the working conditions of full power and minimum water outlet flow of the drinking equipment. For example, the maximum temperature rise per second (Δ T) for full machine power operationmax) At 80 ℃ and at this time the temperature of the feed water (T)ini) At 4 c, the maximum water flow temperature that the machine can deliver is 80 c +4 c to 84 c due to limited energy. Wherein, Delta TmaxSatisfies the following formula (10):

where c is the specific heat capacity of water, ρ is the density of water, v is the pump speed of the water pump, Δ t is the time (e.g., 1s), η is the thermal efficiency of the heating device, and P ismaxTo addMaximum power of the thermal device.
It can be understood that the maximum water outlet temperature
Figure BDA0002740961480000224
The highest water outlet temperature of the drinking water equipment determined according to the local water boiling point meets the following formula (11):

wherein,
Figure BDA0002740961480000226
is the local boiling point of water, Δ TprotectAnd (3) taking the temperature of 1-10 ℃ as the residual protection value for preventing steam injection of the system according to the stability of the system. For example, when boiling point of water

Figure BDA0002740961480000228
At 95-5 deg.c and 90 deg.c.
The control algorithm PID and the like have the function of automatically adjusting output according to the inlet water temperature, so that different environments can reach the target water temperature without exceeding too much. The target water temperature cannot exceed the boiling point of the local water, so that the highest water outlet temperature needs to be set for the machine, and if the highest water outlet temperature is directly set as the local boiling point of the water, the target water temperature is easy to fluctuate to a temperature higher than the boiling point due to certain fluctuation of a control algorithm, so that steam injection is caused, and potential safety hazards are brought. Therefore, the margin Δ T is normally setprotectAnd the system stability is high, 1-3 ℃ is taken, and the system stability is poor, and 3-10 ℃ is taken. In particular, at the temperature (T) of the compensation watercom) Less than or equal to the maximum compensated water temperature

And compensating for the temperature (T) of the watercom) Less than or equal to the maximum water outlet temperature

In the embodiment, the temperature of the compensation water is corrected under the condition that the temperature of the compensation water obtained by judging and calculating is larger than the highest compensation water temperature or the highest outlet water temperature, and the corrected temperature of the compensation water is the lower one of the highest compensation water temperature and the highest outlet water temperature, so that the safety of the water drinking equipment is ensured while the output water temperature is close to the temperature expected by a user, potential safety hazards such as steam spraying are reduced, and the safety of the water drinking equipment in the using process is improved. The highest outlet water temperature is determined according to the boiling point of the local water and the margin protection value, so that potential safety hazards caused by temperature fluctuation such as overshoot and the like in the PID (proportion integration differentiation) control process can be avoided.
In one embodiment, the water dispenser is an instant heating type water dispenser, as shown in fig. 6, in case that it is determined that the residual water temperature does not satisfy the target water intake temperature, outputting the compensation water to be mixed with the residual water comprises the following steps:
step S602, determining that the residual water temperature is less than the target water intaking temperature.
Specifically, the processor of the drinking water equipment can analyze the water getting instruction after receiving the water getting instruction triggered by the user, acquire target water getting temperature information, and compare the residual water temperature and the target water getting temperature, so as to determine that the residual water temperature is less than the target water getting temperature expected by the user.
Step S604, the temperature of the substandard water, of which the temperature output by the instant heating type drinking equipment does not reach the target water taking temperature in the temperature rising process, is obtained.
It can be understood that the instant heating type water dispenser device has short time for waiting for water to be taken by a user, so that in the water outlet process, the instant heating type water dispenser device outputs part of water with the temperature not reaching the target water taking temperature in the heating process. Therefore, the substandard water is the water which is output by the heating device in the heating process and has the temperature which does not meet the target water taking temperature, and the temperature of the substandard water is lower than the target water taking temperature. Wherein, the temperature of the residual water and the temperature of the substandard water can be detected by a temperature sensor of the water outlet pipeline.
Specifically, after the water pump and the heating device are started, the processor acquires the temperature of the substandard water which does not reach the target water taking temperature and is gradually increased by the temperature output by the heating device in the temperature increasing process detected by the temperature sensor of the water outlet pipeline.
And step S606, determining that the temperature of the first mixed water is lower than the target water taking temperature according to the temperature of the residual water and the temperature of the substandard water, wherein the first mixed water is water obtained by mixing the residual water and the substandard water.
It can be understood that the first mixed water is water obtained by mixing the residual water and the substandard water.
Specifically, the processor determines the temperature of first mixed water obtained after mixing the residual water and the substandard water according to the acquired temperature of the residual water and the acquired temperature of the substandard water, and compares the temperature of the first mixed water with the target water taking temperature, thereby determining that the temperature of the first mixed water is less than the target water taking temperature.
In step S608, the compensation water is output to be mixed with the first mixed water, wherein the temperature of the compensation water is higher than the target water intaking temperature.
It can be understood that the compensation water is water which is output from the heating device and has a temperature higher than the target water taking temperature, and is used for carrying out temperature compensation on residual water and substandard water with the temperature lower than the target water taking temperature so as to meet the requirement that a user expects to obtain water meeting the target water taking temperature.
Specifically, under the condition that the temperature of the first mixed water is determined to be smaller than the target water taking temperature, the processor controls the heating device of the instant heating type water drinking equipment to output the compensation water with the temperature higher than the target water taking temperature so as to perform temperature compensation on the temperature of the first mixed water obtained after mixing the residual water and the substandard water, wherein the temperature of the water mixed with the first mixed water meets the target water taking temperature or is close to the target water taking temperature.
In this embodiment, under the circumstances that the residual water temperature is less than target water intaking temperature, through acquireing the residual water temperature of the residual water of persisting in instant heating type drinking water equipment and the temperature of the not up to standard water that does not reach target water intaking temperature of the output of instant heating type drinking water equipment in the temperature rise process, according to the residual water temperature and the temperature of not up to standard water, the temperature of the first mixed water that the surplus water and the not up to standard water mixture obtained is confirmed to be less than target water intaking temperature, thereby the compensation water that the output temperature is higher than target water intaking temperature is in order to mix with first mixed water, in order to carry out temperature compensation to residual water and not up to standard. The method of the embodiment solves the problem that the temperature of the water actually obtained by the user is different from the target water taking temperature, and meets the requirement of the user on high temperature accuracy.
In one embodiment, as shown in fig. 7, determining that the temperature of the first mixed water is less than the target water intake temperature based on the remaining water temperature and the substandard water temperature includes the steps of:

in this embodiment, based on the amount of the determined residual water, the amount of the substandard water, the temperature of the residual water and the temperature of the substandard water, the temperature of the first mixed water can be determined through a specific algorithm, so that the temperature error is reduced, and the accuracy of the temperature control process is improved.
In step S706, it is determined that the temperature of the first mixed water is less than the target intake water temperature.
Specifically, the processor determines the temperature of first mixed water obtained after mixing the residual water and the substandard water according to the acquired temperature of the residual water and the acquired temperature of the substandard water, and compares the temperature of the first mixed water with the target water taking temperature, thereby determining that the temperature of the first mixed water is less than the target water taking temperature.

Wherein m iscomTo compensate for the mass of water, mallM is a preset water intake massSurplusM is the mass of the remaining waterDoes not reach the standardThe quality of the water does not reach the standard.
The processor can control the power of a water pump of the water drinking equipment so as to control the water inlet flow, determine the compensation time according to the determined compensation water amount and the determined water inlet flow, and determine that the output compensation water amount reaches the determined compensation water amount under the condition that the running time reaches the compensation time so as to realize the mixing with the residual water pumped out in advance and the water with the temperature which does not reach the standard in the temperature rising process, thereby obtaining the water with the target water taking temperature or the water close to the target water taking temperature. Further, after entering the forward compensation state, the processor starts to calculate the volume of the water pumped by the water pump in each small time increment step (for example, 0.4s), the integral is solved, if the volume of the pumped water is larger than or equal to the volume of the compensation water, the forward compensation is ended, and the water outlet temperature is controlled to be the target water taking temperature set by the user from the temperature of the compensation water.

In this embodiment, if the amount of the compensation water is known, the target temperature of the water in the user cup is known, the amounts of the residual water and the substandard water are known, and the temperature of the first mixed water is known, the temperature of the compensation water required by the forward compensation can be determined according to the determined known amounts, so that the instant heating type water dispenser is controlled to normally heat the discharged water according to the determined temperature of the compensation water, and the forward compensation for the temperature of the residual water and the temperature of the substandard water is realized.
In one embodiment, as shown in fig. 8, before outputting the compensation water to be mixed with the residual water, the method further includes the steps of:
and S802, determining that the residual water temperature is less than the target water taking temperature.
Specifically, the processor of the drinking water equipment can analyze the water getting instruction after receiving the water getting instruction triggered by the user, acquire target water getting temperature information, and compare the residual water temperature and the target water getting temperature, so as to determine that the residual water temperature is less than the target water getting temperature expected by the user.
And step S804, determining a target residual water temperature according to the target water intaking temperature, wherein the target residual water temperature is not less than the target water intaking temperature.
It is understood that the target residual water temperature is the target temperature that the residual water needs to reach, wherein the target residual water temperature may be equal to or greater than the target water intake temperature.
Specifically, the processor determines the target residual water temperature according to the target intake water temperature, and the specific determination method can be calculated by using the following formula (15):
Figure BDA0002740961480000301
wherein, TtarIs the target residual water temperature, TsetThe temperature of normal temperature water to be provided for the preset winter, namely the target water taking temperature RvolTo compensate for the volume ratio of water volume to residual water,

to compensate for the maximum water temperature of the water, it may be set to a value less than the target water intake temperature, or may be set to a value less than the maximum outlet water temperature of the water dispensing apparatus, e.g., 93 ℃ to 97 ℃.
In the above formula (15), the volume of the compensation water can be determined by the model preset volume and the volume of the residual water, that is, the volume of the residual water is subtracted from the model preset volume, so as to obtain the volume of the compensation water. Furthermore, the volume of the remaining water can be determined by a fixed value stored in advance. At a target water intake temperature (T)set) And maximum temperature of the compensation water

And step 806, starting preheating under the condition that the target residual water temperature is higher than the residual water temperature.
Specifically, the processor compares the target residual water temperature with the residual water temperature after determining the target residual water temperature, and starts the heating device to heat, i.e., starts preheating, to transfer heat of the heating device to the residual water in the water outlet pipeline to increase the residual water temperature under the condition that the target residual water temperature is determined to be greater than the residual water temperature.
And step S808, acquiring the temperature of the preheated residual water.
Specifically, the processor can detect the temperature of the preheated residual water in the water outlet pipeline through the water outlet temperature sensor, so as to obtain the temperature of the preheated residual water.
And step S810, determining that the preheated residual water temperature is less than the target residual water temperature.
Specifically, the processor compares the preheated residual water temperature with a target residual water temperature to determine that the preheated residual water temperature is less than the target residual water temperature.
In this embodiment, before the temperature compensation is performed on the remaining water, the heating device is started to preheat so as to increase the temperature of the remaining water, and the temperature compensation is performed on the remaining water again under the condition that it is determined that the temperature of the preheated remaining water is still less than the target temperature of the remaining water, so that the workload of subsequent temperature compensation can be reduced, the compensation time is shortened, and the process of obtaining the water in the cup meeting the target water taking temperature is accelerated.
In one embodiment, the step of initiating preheating may comprise: determining preheating time according to the amount of the residual water and the temperature increase amount of the preheated residual water; and starting preheating according to the preset preheating time under the condition that the preheating time is determined to be greater than the preset preheating time.
It can be understood that the preheating time is the preheating time, and the rising amount of the preheated residual water temperature is the rising amount of the residual water temperature during the preheating period, and can be determined by the target residual water temperature and the current residual water temperature. The temperature rise amount of the preheated residual water is the difference between the target temperature of the residual water and the residual water temperature, that is, the temperature rise amount of the preheated residual water is the difference between the target temperature of the residual water and the residual water temperature. The preset preheating time is the preset heating time of the machine, such as 3 s.
Specifically, in some embodiments, determining the preheating time based on the amount of the residual water and the preheated residual water temperature increase amount includes determining according to the following equation (16):
Figure BDA0002740961480000311
wherein c is the specific heat capacity of water, ρ is the density of water, VresVolume of residual water, Δ TpreThe temperature of the preheated residual water is increased, eta is the thermal power of the heating device, P is the rated power of the heating device, and delta t is the preheating time.
In practical application, because the temperature of the water inlet is greatly different in the south and north and different seasons, the preheating time should be dynamically changed, and the value of the preheating time can be changed under different inlet water and residual water temperatures.
Specifically, the processor compares the preheating time with a preset preheating time, and when the preheating time is determined to be greater than the preset preheating time, the processor controls the heating device to preheat according to the preset preheating time (for example, 3 s).
In this embodiment, when it is determined that the preheating time is greater than the preset preheating time, the preheating process is cut off when the time for preheating by the processor is up to the preset preheating time, so as to enter the subsequent forward compensation process.
Further, in other embodiments, the step of starting preheating may further include: and starting preheating according to the preheating time under the condition that the preheating time is determined to be less than or equal to the preset preheating time.
Specifically, the processor compares the preheating time with a preset preheating time, and when the preheating time is determined to be less than or equal to the preset preheating time, the processor controls the heating device to preheat according to the preheating time (for example, 3 s).
It can be understood that under the condition that the preheating time is determined to be less than or equal to the preset preheating time, the processor controls the heating device to preheat according to the preheating time, water is normally heated and discharged after preheating is finished, namely, the temperature of the discharged water is controlled, so that the temperature of the discharged water is controlled at the target water taking temperature, and the process does not need to output compensation water with the temperature higher than the target water taking temperature to perform temperature compensation on residual water.

Further, the condition that the residual water temperature does not meet the target water intaking temperature comprises two conditions that the residual water temperature is greater than the target water intaking temperature and the residual water temperature is less than the target water intaking temperature, so that when the residual water temperature is greater than the target water intaking temperature, the compensation water with the output temperature less than the target water intaking temperature performs temperature compensation on the residual water with higher temperature; when the temperature of the residual water is lower than the target water taking temperature, the compensation water with the output temperature higher than the target water taking temperature carries out temperature compensation on the residual water with lower temperature.
Specifically, the processor outputs the compensation water having a temperature greater than the target water intake temperature or the compensation water having a temperature less than the target water intake temperature to be mixed with the residual water when it is determined that the residual water temperature does not satisfy the target water intake temperature, thereby performing temperature compensation on the residual water remaining in the water dispensing apparatus.

In this embodiment, it can be understood that when the volume (V) of the water is compensatedcom) The greater the temperature (T) of the compensation watercom) The closer to the target water intake temperature (T)tar) And, conversely, the temperature (T) of the compensation watercom) With target water intake temperature (T)tar) The larger the difference value is, the temperature of the compensation water is determined through the specific algorithm, so that the water drinking equipment is controlled to normally heat the water according to the temperature of the compensation water, and the forward compensation of the temperature of the residual water is realized.
Furthermore, different application scenes and target water taking temperature ranges can be different, and accurate temperature control can be realized by determining the specific range of the target water taking temperature and then determining the preset water taking amount according to the target water taking temperature.
In some application scenarios, when the target water intake temperature (T)tar) In the range of T1≤Ttar≤T2In which T is1、T2At a lower temperatureAt this time, the water receiving amount is usually small. This situation requires the preferential water receiving amount, i.e. when the temperature range to which the target water taking temperature belongs is T1To T2In time, the processor sets the preset water intake amount to V1And determining the volume of the compensating water at the moment according to the preset water intake quantity set at the moment and the formula (3), and further determining the temperature of the compensating water at the moment according to the determined volume of the compensating water and the formula (5).
In other application scenarios, the target water intake temperature (T)tar) In the range of T3＜Ttar≤T4In which T is3、T4The temperature is higher, and the instantaneous water temperature is not required to be too high, so the water receiving quantity is preferentially controlled, namely, the temperature range of the target water taking temperature is T3To T4In time, the processor can set the preset water intake to be V2And determining the volume of the compensating water at the moment according to the preset water intake quantity set at the moment and the formula (3), and further determining the temperature of the compensating water at the moment according to the determined volume of the compensating water and the formula (5).
In one embodiment, the temperature of the compensation water is above the target water intake temperature, the processor 906 is further configured to: determining that the temperature of the residual water is less than the target water taking temperature; determining the temperature of the compensation water according to the target water intaking temperature; determining the amount of the compensation water according to the temperature of the compensation water, the amount of the residual water, the target water taking temperature and the residual water temperature; outputting the determined amount of the compensation water to be mixed with the remaining water.
Specifically, the processor of the drinking water equipment can analyze the water getting instruction after receiving the water getting instruction triggered by the user, acquire target water getting temperature information, and compare the residual water temperature and the target water getting temperature, so as to determine that the residual water temperature is less than the target water getting temperature expected by the user. The processor determines the temperature of the compensation water at that time according to the temperature range to which the target water intake temperature belongs. The processor determines the amount of the heated compensation water according to the determined temperature of the compensation water, the amount of the residual water, the target water intake temperature and the residual water temperature.
The processor can control the power of a water pump of the water drinking equipment so as to control the water inlet flow, determine the compensation time according to the determined compensation water amount and the water inlet flow, and determine that the output compensation water amount reaches the determined compensation water amount under the condition that the running time reaches the compensation time so as to realize the mixing with the residual water pumped out in advance, thereby obtaining the water with the target water taking temperature or the water close to the target water taking temperature.
Further, in some application scenarios, the target water intake temperature (T)tar) In the range of T5＜Ttar≤T6In which T is5、T6At moderate temperatures, since the above-described water usage scenarios are sensitive to high temperature water, if the compensation water temperature exceeds the target water temperature too high, the nutritional value of the beverage itself may be destroyed. The above-described water usage scenario therefore preferentially controls the temperature of the compensation water.
In this embodiment, under the condition that the temperature of the residual water is lower than the target water intaking temperature, the temperature of the compensation water is determined according to the temperature range to which the target water intaking temperature belongs, and then the amount of the compensation water is determined according to the temperature of the compensation water, so that the compensation water with the determined amount and the temperature higher than the target water intaking temperature is output according to the determined amount of the compensation water to be mixed with the residual water, and the temperature error of the actually obtained water is reduced, so that accurate temperature control is realized.
In one embodiment, the temperature of the compensation water is the target water intake temperature plus a positive offset value.
It will be appreciated that the positive offset value is a preset maximum allowable temperature offset, which may be set by a user or by default to the system, for example, 10 ℃.
Specifically, when the target intake water temperature (T)tar) In the range of T5＜Ttar≤T6When the temperature of the compensation water at this time is the target intake water temperature plus a positive offset value, for example, when the target intake water temperature is 60 ℃ and the positive offset value is 10 ℃, the temperature (T) of the compensation water at this time is determinedcom) The value of (b) is 60 ℃ +10 ℃ + 70 ℃.
In some application scenarios, the temperature of the compensation water calculated according to the formula (6) is high, the drinking water equipment cannot be realized, and secondary compensation is required, wherein the secondary compensation is a process of performing temperature compensation on the residual water according to the corrected temperature of the compensation water.
In one embodiment, the processor 906 is further configured to: the amount of make-up water is determined according to the following equation (7):

to compensate for the highest water temperature, TiniFor inlet water temperature, Δ TmaxThe temperature of water flow flowing through the heating device is raised under the working conditions of full power and minimum water outlet flow of the drinking equipment. For example, the maximum temperature rise per second (Δ T) for full machine power operationmax) At 80 ℃ and at this time the temperature of the feed water (T)ini) At 4 c, the maximum water flow temperature that the machine can deliver is 80 c +4 c to 84 c due to limited energy. Wherein, Delta TmaxSatisfies the following formula (10):

The PID control algorithm has the function of automatically adjusting output according to the inlet water temperature, so that different environments can reach the target water temperature without the risk ofToo much beyond. The target water temperature cannot exceed the boiling point of the local water, so that the highest water outlet temperature needs to be set for the machine, and if the highest water outlet temperature is directly set as the local boiling point of the water, the target water temperature is easy to fluctuate to a temperature higher than the boiling point due to certain fluctuation of a control algorithm, so that steam injection is caused, and potential safety hazards are brought. Therefore, the margin Δ T is normally setprotectAnd the system stability is high, 1-3 ℃ is taken, and the system stability is poor, and 3-10 ℃ is taken.

The highest outlet water temperature is determined according to the boiling point of the local water and the margin protection value, so that potential safety hazards caused by temperature fluctuation such as overshoot and the like in the PID (proportion integration differentiation) control process can be avoided.

It can be understood that the instant heating type water dispenser device has short time for waiting for water to be taken by a user, so that in the water outlet process, the instant heating type water dispenser device outputs part of water with the temperature not reaching the target water taking temperature in the heating process. Therefore, the substandard water is the water which is output by the heating device in the heating process and has the temperature which does not meet the target water taking temperature, and the temperature of the substandard water is lower than the target water taking temperature. Wherein, the temperature of the residual water and the temperature of the substandard water can be detected by a temperature sensor of the water outlet pipeline. It can be understood that the first mixed water is water obtained by mixing the residual water and the substandard water. The compensation water is water with the temperature higher than the target water taking temperature and output from the heating device, and is used for carrying out temperature compensation on residual water and substandard water with the temperature lower than the target water taking temperature so as to meet the requirement that a user expects to obtain the water meeting the target water taking temperature.
Specifically, the processor of the drinking water equipment can analyze the water getting instruction after receiving the water getting instruction triggered by the user, acquire target water getting temperature information, and compare the residual water temperature and the target water getting temperature, so as to determine that the residual water temperature is less than the target water getting temperature expected by the user. After the water pump and the heating device are started, the processor acquires the temperature of the substandard water which does not reach the target water taking temperature and is gradually increased by the temperature output by the heating device in the temperature increasing process detected by the temperature sensor of the water outlet pipeline. The processor determines the temperature of first mixed water obtained after the residual water and the substandard water are mixed according to the acquired temperature of the residual water and the acquired temperature of the substandard water, and compares the temperature of the first mixed water with the target water taking temperature, so that the temperature of the first mixed water is determined to be smaller than the target water taking temperature. Under the condition that the temperature of the first mixed water is determined to be smaller than the target water taking temperature, the processor controls the heating device of the instant heating type water drinking equipment to output the compensation water with the temperature higher than the target water taking temperature so as to perform temperature compensation on the temperature of the first mixed water obtained after mixing the residual water and the substandard water, and the temperature of the water mixed by the compensation water and the first mixed water meets the target water taking temperature or is close to the target water taking temperature.

It is understood that the amount of residual water may be a fixed value stored in advance, may be detected by a water flow sensor, or may be obtained by geometric modeling. The amount of substandard water may be determined by a specific algorithm.
Specifically, the processor acquires the amount of residual water detected by a water flow sensor of the water outlet pipeline or the amount of residual water obtained through geometric modeling, integrates the pump speed of the water pump determined based on the driving value of the water pump during the temperature rise period, and determines the amount of substandard water during the period. The processor may determine the temperature of the first mixed water based on the amount of remaining water, the amount of substandard water, the temperature of the remaining water, and the temperature of the substandard water based on a specific algorithmic model. The processor determines the temperature of first mixed water obtained after the residual water and the substandard water are mixed according to the acquired temperature of the residual water and the acquired temperature of the substandard water, and compares the temperature of the first mixed water with the target water taking temperature, so that the temperature of the first mixed water is determined to be smaller than the target water taking temperature.
The device in this embodiment, through the volume that acquires the surplus water and the volume of not up to standard water, thereby according to the volume of surplus water, the volume of not up to standard water, the temperature of surplus water temperature and not up to standard water's temperature determination first mixed water, and compare the temperature and the target water intaking temperature of first mixed water, the temperature of confirming first mixed water is less than target water intaking temperature, introduce the volume of surplus water and corresponding temperature, the volume of not up to standard water and corresponding temperature, thereby the temperature of the first mixed water after the surplus water and not up to standard water mix is confirmed accurately, in order to realize the accurate nature of temperature control process.

The formula (13) can be derived from the following formulas (13-1) and (13-2), which can be derived from the law of conservation of energy:
Figure BDA0002740961480000462
thus, it is possible to obtain:
Vsurplus(Tmix1-TSurplus)＝VDoes not reach the standard(TDoes not reach the standard-Tmix1) Formula (13-2)
In the formula (13-1), TDoes not reach the standardRepresenting the temperature of the outflowing water in real time as detected by the outflowing water temperature sensor during the temperature rise, CwIs the specific heat capacity of water, pwIs the density of water.
The water outlet process of the instant heating type drinking equipment can be controlled by the single chip microcomputer, the water outlet process has a certain control step length, generally 20ms, and in each execution step length, the flow of the water pump is unchanged, namely the heating power of the heat pipe is unchanged. Thus, the non-compliance water-related integral term can be discretized into the following equation (13-3) to solve for:
Figure BDA0002740961480000463
the device in this embodiment, based on the volume of the surplus water of confirming, the volume of not up to standard water, surplus water temperature and the temperature of not up to standard water, can confirm the temperature of first mixed water through specific algorithm to reduce the temperature error, improve the accuracy nature of temperature control process.
In one embodiment, the processor 906 is further configured to: determining the amount of compensation water according to the preset water intake amount, the residual water amount and the amount of substandard water; outputting the determined amount of the compensation water to be mixed with the first mixed water.
It can be understood that the preset water intake amount is the water outlet amount of the primary water outlet preset by the instant heating type drinking water device, wherein the amount can be volume, for example, 120ml, or mass, for example, 120 g.
Specifically, the processor determines the amount of the compensation water according to the preset water intake amount, the amount of the residual water and the amount of the substandard water, and further, the amount of the compensation water is the preset water intake amount minus the amount of the residual water and the amount of the substandard water, wherein the amount can be volume or mass.
When the equivalent is the volume, when the total volume of water in the cup of the user is set to reach the preset water intake amount, the compensation is completed, so that the water temperature in the cup is the set target water intake temperature, and the volume of the compensation water is the volume of the preset water intake volume minus the volume of the residual water and the volume of the substandard water, which can be specifically referred to the following formula (13-4):
Vcom＝Vall-Vsurplus-VDoes not reach the standardFormula (13-4)
Wherein, VcomTo compensate for the volume of water, VallTo preset the volume of water intake, VSurplusVolume of residual water, VDoes not reach the standardVolume of substandard water.
When the equivalent is the mass, introducing the density of the water on the basis of the formula (13-4), and the mass of the compensation water is the mass of the preset water intake minus the mass of the residual water and the mass of the substandard water, which can be specifically seen in the following formula (13-5):
mcom＝mall-msurplus-mDoes not reach the standardFormula (13-5)
Wherein m iscomTo compensate for the mass of water, mallM is a preset water intake massSurplusM is the mass of the remaining waterDoes not reach the standardThe quality of the water does not reach the standard.
The processor can control the power of a water pump of the water drinking equipment so as to control the water inlet flow, determine the compensation time according to the determined compensation water amount and the determined water inlet flow, and determine that the output compensation water amount reaches the determined compensation water amount under the condition that the running time reaches the compensation time so as to realize the mixing with the residual water pumped out in advance and the water with the temperature which does not reach the standard in the temperature rising process, thereby obtaining the water with the target water taking temperature or the water close to the target water taking temperature. Further, after entering the forward compensation state, the processor starts to calculate the volume of the water pumped by the water pump in each small time increment step (for example, 0.4s), the integral is solved, if the volume of the pumped water is larger than or equal to the volume of the compensation water, the forward compensation is ended, and the water outlet temperature is controlled to be the target water taking temperature set by the user from the temperature of the compensation water.
The device in this embodiment, through the volume of confirming the compensating water according to the volume of predetermineeing water intaking volume, surplus water and the volume of not up to standard water, the compensating water that volume output temperature is higher than target water intaking temperature according to the compensating water mixes with the first mixed water after surplus water and the water that does not up to standard mixes, can reduce temperature deviation, realizes accurate accuse temperature.
In one embodiment, the processor 906 is further configured to: and determining the temperature of the compensation water according to the amount of the residual water, the amount of the substandard water, the temperature of the first mixed water, the target water taking temperature and the amount of the compensation water.
Specifically, the processor determines the temperature of the heated compensation water according to the amount of the residual water, the amount of the substandard water, the temperature of the first mixed water, the target water intake temperature and the amount of the compensation water.
The device in this embodiment adjusts the power of the heating device and the power of the water pump through the control algorithms such as PID control and the like by determining the temperature of the compensation water, so as to output the water meeting the temperature of the compensation water, realize the mixing with the residual water and the water not meeting the standard, and further obtain the water meeting the target water taking temperature.
In one embodiment, the processor 906 is further configured to: the temperature of the compensation water is determined according to the following equation (14):
Figure BDA0002740961480000481
wherein, TcomTo compensate for the temperature of the water, VSurplusVolume of residual water, VDoes not reach the standardVolume of water not meeting the standard, TtarTemperature of water taken for target, Tmix1Is the temperature of the first mixed water, VcomTo compensate for the volume of water.
According to the device in the embodiment, the amount of the compensation water is known, the target temperature of the water in the user cup is known, the amounts of the residual water and the substandard water are known, and the temperature of the first mixed water is known, so that the temperature of the compensation water required by the forward compensation can be determined according to the determined known amounts, the instant heating type water dispenser is controlled to normally heat the discharged water according to the determined temperature of the compensation water, and the forward compensation of the temperature of the residual water and the temperature of the substandard water is realized.
In one embodiment, the processor 906 is further configured to: determining that the temperature of the residual water is less than the target water taking temperature; determining a target residual water temperature according to the target water intaking temperature, wherein the target residual water temperature is not less than the target water intaking temperature; starting preheating under the condition that the target residual water temperature is higher than the residual water temperature; obtaining the temperature of the preheated residual water; and determining that the temperature of the preheated residual water is less than the target temperature of the residual water.
It is understood that the target residual water temperature is the target temperature that the residual water needs to reach, wherein the target residual water temperature may be equal to or greater than the target water intake temperature.
Specifically, the processor of the drinking water equipment can analyze the water getting instruction after receiving the water getting instruction triggered by the user, acquire target water getting temperature information, and compare the residual water temperature and the target water getting temperature, so as to determine that the residual water temperature is less than the target water getting temperature expected by the user. The processor determines the target residual water temperature according to the target water intake temperature, and the specific determination method can adopt the following formula (15) to calculate:
Figure BDA0002740961480000491
wherein, TtarIs the target residual water temperature, TsetThe temperature of normal temperature water to be provided for the preset winter, namely the target water taking temperature RvolTo compensate for the volume ratio of water volume to residual water,
Figure BDA0002740961480000492
to compensate for the maximum water temperature of the water, it may be set to a value less than the target water intake temperature, or may be set to a value less than the maximum outlet water temperature of the water dispensing apparatus, e.g., 93 ℃ to 97 ℃.
In the above formula (15), the volume of the compensation water can be determined by the model preset volume and the volume of the residual water, that is, the volume of the residual water is subtracted from the model preset volume, so as to obtain the volume of the compensation water. Furthermore, the volume of the remaining water can be determined by a fixed value stored in advance. At a target water intake temperature (T)set) And maximum temperature of the compensation water
Figure BDA0002740961480000493
Set to equal values, at which time the target residual water temperature (T)tar) With target water intake temperature (T)set) Are set to equal values.
And after the processor determines the target residual water temperature, the target residual water temperature is compared with the residual water temperature, and under the condition that the target residual water temperature is greater than the residual water temperature, the heating device is started to heat, namely, the preheating is started, so that the heat of the heating device is transferred to the residual water in the water outlet pipeline, and the residual water temperature is increased. The processor can detect the temperature of the preheated residual water in the water outlet pipeline through the water outlet temperature sensor, so as to obtain the temperature of the preheated residual water. The processor compares the preheated residual water temperature with a target residual water temperature to determine that the preheated residual water temperature is less than the target residual water temperature.
The device in the embodiment starts the heating device to preheat before the temperature compensation is carried out on the residual water so as to improve the temperature of the residual water, and then carries out the temperature compensation on the residual water under the condition that the temperature of the preheated residual water is still less than the target temperature of the residual water, so that the workload of the follow-up temperature compensation can be reduced, the compensation time is shortened, and the process of obtaining the water in the cup meeting the target water taking temperature is accelerated.
In one embodiment, the processor 906 is further configured to: determining preheating time according to the amount of the residual water and the temperature increase amount of the preheated residual water; and starting preheating according to the preset preheating time under the condition that the preheating time is determined to be greater than the preset preheating time.
It can be understood that the preheating time is the preheating time, and the rising amount of the preheated residual water temperature is the rising amount of the residual water temperature during the preheating period, and can be determined by the target residual water temperature and the current residual water temperature. The temperature rise amount of the preheated residual water is the difference between the target temperature of the residual water and the residual water temperature, that is, the temperature rise amount of the preheated residual water is the difference between the target temperature of the residual water and the residual water temperature. The preset preheating time is the preset heating time of the machine, such as 3 s.
Specifically, in some embodiments, determining the preheating time based on the amount of the residual water and the preheated residual water temperature increase amount includes determining according to the following equation (16):
Figure BDA0002740961480000501
wherein c is the specific heat capacity of water, ρ is the density of water, VresVolume of residual water, Δ TpreThe temperature of the preheated residual water is increased, eta is the thermal power of the heating device, P is the rated power of the heating device, and delta t is the preheating time.
In practical application, because the temperature of the water inlet is greatly different in the south and north and different seasons, the preheating time should be dynamically changed, and the value of the preheating time can be changed under different inlet water and residual water temperatures.
Specifically, the processor compares the preheating time with a preset preheating time, and when the preheating time is determined to be greater than the preset preheating time, the processor controls the heating device to preheat according to the preset preheating time (for example, 3 s).
