To this end, a first aspect of the present invention proposes a control method of a water treatment apparatus.

A second aspect of the present invention provides a control device for a water treatment apparatus.

A fourth aspect of the invention is directed to a readable storage medium.

A fifth aspect of the present invention provides a water treatment apparatus.

In view of this, a first aspect of the present invention provides a control method for a water treatment apparatus including a water pump, the control method including: responding to a water outlet instruction, and acquiring a first voltage of the water pump; determining a corresponding target adjustment coefficient according to the first voltage; determining a first flow rate based on the target adjustment factor and the first voltage; and controlling the water outlet of the water treatment device according to the first flow.

In the technical scheme, the water treatment device comprises an instant heating type water dispenser, the instant heating type water dispenser comprises a water inlet pipeline, an instant heating module, a water outlet pipeline and a water pump, wherein the instant heating module is respectively connected with the water inlet pipeline and the water outlet pipeline, the water pump is arranged on the side of the water inlet pipeline, cold water is pumped to the instant heating module through the water inlet pipeline, and after the cold water is heated through the instant heating module, hot water supply with constant flow and constant temperature is formed.

After the water outlet temperature and the water outlet quantity are set by a user, the heating power of the instant heating module and the power-on time of the water pump are calculated by the instant heating type water dispenser according to the flow of the water pump, so that accurate temperature control and accurate control of the water outlet quantity are realized.

The flow of the water pump is generally calibrated when leaving a factory, and a pipeline connected with the water pump is fixed during calibration. Due to different product designs, different water dispensers using the same water pump have different water path designs, such as the structural layout of internal pipelines. In actual products, the length, the number of elbows, the pipe diameter and even the installation height of the water dispenser of a waterway pipeline all affect the pump water flow of a water pump, so that the actual flow of the water dispenser cannot be accurately expressed by the factory-calibrated water pump flow, and inaccurate temperature control and flow control are caused.

In order to solve the existing problems, the embodiment of the application firstly determines the first voltage of the water pump after receiving the water outlet instruction. Specifically, the first voltage is a real-time working voltage of the water pump, the first voltage can express the pumping output of the current water pump, and it can be understood that the higher the first voltage is, the larger the pumping output of the water pump is, and otherwise, the lower the first voltage is, the smaller the pumping treatment of the water pump is.

In some embodiments, the first voltage of the water pump can be reported to a control board of the water dispenser by the water pump, so that the first voltage can be accurately identified.

In other embodiments, a corresponding voltage detection module can be further arranged, the first voltage of the water pump is detected in real time through the voltage detection module, and the embodiment of the application is not limited to this.

After the first voltage is obtained, the main control module of the water dispenser obtains a target adjustment coefficient corresponding to the first voltage, wherein the target adjustment coefficient is a 'pipeline loss coefficient' of the instant water dispenser internal water pump, that is, a difference between a standard pump water flow (i.e., a rated pump water flow) of the water pump and an actual pump water flow in an ideal state, and the actual pump water flow under the current water dispenser internal pipeline structure, that is, the first flow, can be calculated according to the target adjustment coefficient when the water pump pumps water under the driving of the first voltage.

The corrected first flow is used for controlling the water treatment device, such as an instant heating type water dispenser to discharge and heat water, so that the condition that the actual pump water flow of the water pump is not consistent with the designed pump water flow due to the design of an internal pipeline of the water dispenser, the finally caused condition that the discharged water temperature is not consistent with the set value or the discharged water amount is not consistent with the set value can be effectively avoided, and more accurate water discharge is realized.

According to the embodiment of the application, the actual pump water flow of the water pump is accurately determined based on the working voltage of the water pump and the corresponding target adjustment coefficient, so that the instant heating module and the water outlet of the water dispenser are accurately controlled based on the determined first flow, the accurate water outlet and the accurate temperature control are ensured, and the use experience of the instant heating type water dispenser is improved.

In addition, the control method of the water treatment device in the above technical solution provided by the present invention may further have the following additional technical features:

in the above technical solution, determining the first flow rate based on the target adjustment coefficient and the first voltage includes: determining a second flow rate according to the first voltage and the first relational expression, wherein the second flow rate is the rated flow rate of the water pump when the water pump works at the first voltage; and determining the first flow rate according to the product of the second flow rate and the target adjusting coefficient.

In the technical scheme, when the actual flow of the water pump of the instant heating type water dispenser is determined, firstly, the second flow is calculated according to the collected real-time working voltage of the water pump, namely the first voltage, and a pre-stored first relational expression. Specifically, the calculated second flow rate is a rated flow rate corresponding to the current instant heating type water dispenser, namely, a water pump of the water treatment device when the instant heating type water dispenser is driven to work by the first voltage. That is, when the water pump of the water treatment device is in an ideal state and receives the driving signal of the first voltage, the theoretical value of the pump water flow rate is the second flow rate.

After the water pump is installed in a water treatment device, such as an instant heating type water dispenser, the design of the internal pipelines of the instant heating type water dispenser is different, and the length of the water path, the bending number of the pipelines and the pipe diameter of the pipelines are also different from the ideal state, so that the theoretical pump water flow of the water pump can generate pipeline loss, and the first relational expression can accurately reflect the relational expression between the driving voltage of the water pump and the theoretical pump water flow (rated flow, namely second flow) under the ideal state, namely when the water pump is only connected with an extreme pipeline (or not connected with the pipeline), and under the condition of no pipeline loss.

Therefore, according to the real-time working voltage, namely the first voltage, of the water pump actually acquired at present, and by combining the pre-stored first relational expression, the pump water flow rate, namely the second flow rate, of the water pump in the ideal state can be accurately obtained.

And then, calculating the actual pump water flow of the water pump according to the theoretical pump water flow and the corresponding target adjustment coefficient. Specifically, the target adjustment coefficient is related to the pipeline loss of the water pump in the instant heating type water dispenser, and the actual pump water flow rate, i.e., the first flow rate, under the current internal pipeline structure of the water dispenser when the water pump pumps water under the driving of the first voltage can be calculated according to the target adjustment coefficient, i.e., the difference between the standard pump water flow rate and the actual pump water flow rate of the water pump in an ideal state.

The instant heating type water dispenser is controlled to discharge water and heat through the corrected first flow, so that the problem that the actual pump water flow of the water pump is inconsistent with the designed pump water flow due to the design of an internal pipeline of the water dispenser can be effectively avoided, and more accurate water discharge is realized.

In any of the above technical solutions, the first relational expression is a relational expression between an operating voltage of the reference water pump and a rated pump water flow rate of the reference water pump.

In the technical scheme, the second flow of the water pump is determined according to the first voltage, namely the collected real-time working voltage of the water pump, and the first relational expression, namely the rated pumping water flow of the water pump when the driving voltage of the water pump is the first voltage in an ideal state.

The first relational expression can reflect the corresponding relation between different working voltages of the reference water pump and different rated pump water flow rates of the reference water pump. The reference water pump specifically refers to a water pump installed in a water treatment device, such as an instant heating type water dispenser, and the pump water flow rate when only an extreme pipeline is connected is the standard pump water flow rate when the water pump with the same model and the same parameter as the water pump installed in the current water treatment device is not affected by the pipeline.

The method comprises the steps of acquiring a plurality of working voltages of a reference water pump, acquiring rated pump water flow of the reference water pump under the working voltages, determining and obtaining a first relational expression, calculating the rated pump water flow of the current instant heating type water dispenser water pump under real-time working voltages based on the first relational expression, and adjusting and correcting the pump water flow through a target adjustment coefficient, so that the instant heating type water dispenser can calculate the pump water flow more accurately, the accuracy of water flow calculation and temperature calculation is improved, and the water outlet effect is improved.

In any of the above technical solutions, determining a corresponding target adjustment coefficient according to the first voltage includes: determining a target adjustment coefficient according to the first voltage and the second relational expression; the second relational expression is a relational expression of the working voltage of the reference water pump and a preset adjusting coefficient, the working voltage of the reference water pump comprises the first voltage, and the preset adjusting coefficient comprises a target adjusting coefficient.

In the technical scheme, after the current real-time working voltage, namely the first voltage, of the water pump is collected, a target adjustment coefficient is further determined, and specifically, the target adjustment coefficient suitable for correcting the real-time pump water flow of the water pump is determined through the first voltage and a pre-stored second relational expression.

Specifically, the second relational expression can reflect a corresponding relationship between a standard pumping capacity (rated pumping capacity) of the reference water pump, that is, the water pump which is not affected by the pipeline loss, and an actual pumping capacity of the water pump installed in the instant heating type water dispenser under the influence of the internal pipeline of the instant heating type water dispenser.

It can be understood that, because the internal pipeline of the instant heating type water dispenser can have a bad influence on the actual water pumping flow of the water pump, in the actual use process, the water pumping capacity of the water pump in the instant heating type water dispenser can be weaker than the rated water pumping capacity of the same water pump in an ideal state (when an extremely short pipeline is connected).

Therefore, the actual pump water flow of the water pump of the instant heating type water dispenser is compensated and adjusted through the second relational expression, namely, the second flow of the water pump is adjusted through the second relational expression to obtain the actual flow of the water pump, namely, the first flow, and the instant heating module and the outlet water of the water dispenser are accurately controlled through the adjusted first flow, so that the accuracy of the outlet water quantity and the accuracy of temperature control are ensured, and the use experience of the instant heating type water dispenser is improved.

In any of the above solutions, before determining the second flow rate, the control method further includes: acquiring N second voltages and corresponding N first rated pump water flows, wherein N is a positive integer, the second voltages are preset working voltages of a reference water pump, and the second voltages comprise first voltages; determining a first relational expression according to the corresponding relation between the N second voltages and the N first rated pump water flow rates

In the technical scheme, when the instant heating type water dispenser leaves a factory, a first relational expression of the actual working voltage and the rated pump water flow of the water pump is determined according to the selected water pump and the set water path, and is pre-stored in control equipment of the instant heating type water dispenser, so that when the instant heating type water dispenser works, the rated pump water flow of the water pump under the current working voltage can be determined through the first relational expression, the actual pump water flow of the water pump is determined and compensated, and the water temperature regulation precision and the water outlet regulation precision of the instant heating type water dispenser can be improved.

Specifically, N standard operating voltages of the reference water pump, that is, the N second voltages may be taken, and the N standard operating voltages are all within a range of a rated operating voltage of the reference water pump. It can be understood that the more the number of standard operating voltages taken by the experiment, the more dense the distribution, the higher the experimental effect.

After N standard working voltages are obtained, a standard flow experiment, namely an extremely short pipeline experiment, is carried out on the reference water pump according to the N standard working voltages. Specifically, the reference water pump is connected to a very short pipeline, wherein the very short pipeline refers to a pipeline length that does not cause loss or other influences on the pump water flow of the water pump, and the actual pump water flow of the water pump is the same as the rated pump water flow when the very short pipeline is connected.

In the experimental process, the reference water pump is driven to pump water through N standard working voltages respectively, and the standard pump water flow of the water pump driven by each working voltage is collected through a flowmeter, wherein the pump water flow is the rated pump water flow of the water pump.

With N standard operating voltages including voltage Va₁Voltage Va₂… … Voltage Va_nFor example, the corresponding first rated pump water flow rate includes the flow rate Q_{Standard 1}Flow rate Q_{Standard 2}… … flow rate Q_{Standard n}And each working voltage corresponds to one standard flow.

According to Va₁、Va₂……Va_nAnd Q_{Standard 1}、Q_{Standard 2}……Q_{Standard n}The corresponding relation between the actual working voltage of the reference water pump and the standard pump water flow of the reference water pump, namely the first relational expression of the rated pump water flow, which is also the relational function between the standard flow and the voltage of the reference water pump, can be obtained and recorded as:

Q_{standard of reference}＝f(V)，V＝Va₁、Va₂……Va_n；

Wherein Q is_{Standard of merit}The standard flow of the reference water pump is shown, and V is the standard working voltage of the reference water pump.

The rated pump water flow of the water pump of the current instant heating type water dispenser under the real-time working voltage is calculated through the first relational expression, and then the pump water flow is adjusted and corrected through the target adjustment coefficient, so that the pump water flow of the instant heating type water dispenser can be calculated more accurately, the accuracy of water flow calculation and temperature calculation is improved, and the water outlet effect is improved.

In any of the above technical solutions, before determining the target adjustment coefficient, the control method further includes: determining M second rated pumping water flow rates corresponding to M third voltages based on the first relational expression, wherein M is a positive integer; acquiring M actual pumping water flows of the water pump under M third voltages respectively, wherein the M actual pumping water flows correspond to M second rated pumping water flows one by one; determining M preset adjustment coefficients corresponding to each third voltage according to the ratio of the actual pumping water flow and the second rated pumping water flow corresponding to each M third voltages; and fitting to obtain a second relational expression according to the M third voltages and the M preset adjustment coefficients.

According to the technical scheme, when the instant heating type water dispenser leaves a factory, a first relational expression of the actual working voltage and the rated pump water flow of the water pump is pre-stored, and when the instant heating type water dispenser works, the rated pump water flow of the water pump under the current working voltage can be determined through the first relational expression.

And after the rated pump water flow is obtained, determining a target adjustment coefficient suitable for correcting the real-time pump water flow of the water pump through a second relational expression.

Specifically, the second relational expression can reflect a corresponding relationship between a standard water pumping capacity of a reference water pump, that is, a water pump which is not affected by pipeline loss, and an actual water pumping capacity of a water pump installed in the instant heating type water dispenser under the influence of an internal pipeline of the instant heating type water dispenser. And adjusting the second flow of the water pump through the second relational expression to obtain the actual flow of the water pump, namely the first flow, and accurately controlling the instant heating module and the water outlet of the water dispenser through the adjusted first flow to ensure the accuracy of the water outlet quantity and the accuracy of temperature control.

Specifically, M standard operating voltages, namely the M third voltages, currently installed in the water pump of the instant heating type water dispenser are obtained, and the M standard operating voltages are all within the range of the rated operating voltage of the water pump installed in the instant heating type water dispenser. It can be understood that the more the number of standard operating voltages taken by the experiment, the more dense the distribution, the higher the experimental effect.

After M standard operating voltages (i.e., the third voltages) are obtained, the rated pumping water flow rates corresponding to the M standard operating voltages are respectively calculated through the first relational expression, and M second rated pumping water flow rates corresponding to the M standard operating voltages one to one are obtained.

After M second rated pump water flows are obtained, a flow experiment is carried out on the whole instant heating type water dispenser, specifically, M standard working voltages (third voltages) are respectively used for driving a water pump of the instant heating type water dispenser to work, and a flowmeter is used for collecting the actual water flow of the instant heating type water dispenser under the driving of each third voltage, so that M actual water flows are obtained, namely M actual pump water flows of a water pump in the instant heating type water dispenser, and the M actual pump water flows correspond to the M second rated pump water flows one by one.

Here, a preset adjustment coefficient k is defined as Q_{Complete machine}÷Q_{Standard of merit}；

Wherein k is a preset adjustment coefficient, Q_{Complete machine}Is the actual pump water flow Q of the water pump in the instant heating type water dispenser_{Standard of merit}The water pump is the standard pump water flow of the same type water pump when being connected with a very short pipeline, namely the rated pump water flow.

Suppose that the M third voltages are Vc₁、Vc₂……Vc_mThe M second rated pump water flow rates include: q_{Complete machine 1}、Q_{Complete machine 2}……Q_{Whole machine m}Correspondingly, the M second rated pumping water flow rates include: q_{Standard 1}、Q_{Standard 2}……Q_{Standard m}。

Thus, defining the preset adjustment factor comprises k₁、k₂……k_mAnd satisfies the following formula:

k₁＝Q_{complete machine 1}÷Q_{Standard 1}；

k₂＝Q_{Complete machine 2}÷Q_{Standard 2}；

……

k_m＝Q_{Whole machine m}÷Q_{Standard m}。

Wherein k is₁And Vc₁Is a set of data, k₂And Vc₂As a set of data … … k_mAnd Vc_mThe method is a group of data, wherein a coefficient k represents the influence of a complete machine water inlet and outlet pipeline of the instant heating type water dispenser on the flow of a water pump, namely the actual flow of the water pump on the pipeline is k times of the standard flow of the water pump of the type under the same driving voltage.

After obtaining the above experimental data, k is added₁、k₂……k_mAnd Vc₁、Vc₂……Vc_mFitting to the corresponding functional relation: k ═ f (v), giving rise to a second relation,the actual pump water flow of the water pump of the instant heating type water dispenser is compensated and adjusted through the second relational expression, namely, the second flow of the water pump is adjusted through the second relational expression to obtain the actual flow of the water pump, namely, the first flow, and the instant heating module and the water outlet of the water dispenser are accurately controlled through the adjusted first flow, so that the accuracy of the water outlet and the accuracy of temperature control are ensured, and the use experience of the instant heating type water dispenser is improved.

In any one of the above technical solutions, the number of the second relational expressions is M-1; according to the M third voltages and the M preset adjustment coefficients, fitting to obtain a second relational expression, which comprises the following steps: and fitting to obtain a second relational expression corresponding to a target voltage range according to the O-th third voltage in the M third voltages and the O-th adjustment coefficient in the M preset adjustment coefficients, wherein the target voltage range is greater than or equal to the O-1-th third voltage and smaller than the O-th third voltage, and O is a positive integer smaller than M.

In the technical scheme, in order to improve the accuracy of the target adjustment coefficient and further improve the accuracy of flow calculation and the flow control effect of the instant heating type water dispenser, the second relational expression is divided into M-1 piecewise function relational expressions according to the voltage range of the current working voltage.

Specifically, M-1 piecewise functions respectively correspond to M-1 voltage ranges, and the M-1 voltage ranges include: [ Vc ]₁，Vc₂)、[Vc₂，Vc₃)……[Vc_m-1，Vc_m) For each voltage range, a piecewise function relation is independently set, specifically, the piecewise function includes:

k＝f₁(V)＝a₁×V+b₁，Vc₁≤V＜Vc₂；

k＝f₂(V)＝a₂×V+b₂，Vc₂≤V＜Vc₃；

……

k＝f_m-1(V)＝a_m-1×V+b_m-1，Vc_m-1≤V＜Vc_m。

the above piecewise equation can be expressed as:

k＝f_o(V)＝a_o×V+b_o，Vc_o-1≤V＜Vc_o。

k is a preset adjustment coefficient, a and b are constants, Vc is a third voltage, and V is a first voltage.

After the real-time working voltage, namely the first voltage, of the water pump of the instant heating water dispenser is collected, firstly, the voltage range corresponding to the first voltage is judged, so that in the piecewise function, a target relational expression is determined, a target adjustment coefficient is obtained through calculation of the target relational expression, and according to the target adjustment coefficient, when the water pump pumps water under the driving of the first voltage, the actual water pumping flow, namely the first flow, of the water pump under the current internal pipeline structure of the water dispenser can be calculated. The instant heating type water dispenser is controlled to discharge water and heat through the corrected first flow, so that the problem that the actual pump water flow of the water pump is inconsistent with the designed pump water flow due to the design of an internal pipeline of the water dispenser can be effectively avoided, and more accurate water discharge is realized.

In any of the above technical solutions, the first flow rate is a current pump water flow rate of the water pump; controlling water output of a water treatment device according to a first flow rate, comprising: determining target water yield according to the water outlet instruction; determining the water pumping time according to the first flow and the target water yield; and controlling the water pump to continuously pump water in the water pumping time.

In the technical scheme, the first flow is specifically an actual pumping flow of the instant heating type water dispenser, that is, a pumping amount under the influence of a pipeline of the instant heating type water dispenser. When a water outlet instruction is received, firstly, a target water outlet amount corresponding to the water outlet instruction and a target water temperature corresponding to the water outlet instruction are determined.

And controlling the instant heating module of the instant heating type water dispenser to work according to the target water temperature and the first flow, so that the heating power of the instant heating module is adjusted according to the first flow, and the accurate adjustment of the water temperature is realized.

Meanwhile, according to the target water yield and the first flow, calculating to obtain the corresponding water pumping time length, and the product of the water pumping time length and the first flow, namely the target water yield. In the water outlet process, the water pump is driven to continuously pump water within the water pumping time according to the corresponding driving voltage, so that accurate water outlet matched with the target water outlet amount is obtained, the accurate water outlet amount and the accurate temperature control are ensured, and the use experience of the instant heating type water dispenser is improved.

And because the product design is different, the water route design of different water dispensers using the same water pump, such as the structural layout of the internal pipeline, can also be different. In actual products, the length, the number of elbows, the pipe diameter and even the installation height of the water dispenser of a waterway pipeline all affect the pump water flow of a water pump, so that the actual flow of the water dispenser cannot be accurately expressed by the factory-calibrated water pump flow, and inaccurate temperature control and flow control are caused.
