The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

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 device.

A third aspect of the present invention proposes a control device for a water treatment apparatus.

A fourth aspect of the invention proposes 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 of a water treatment apparatus including a water pump, the control method comprising: responding to a water outlet instruction, and acquiring a first voltage of a water pump; determining a corresponding target adjustment coefficient according to the first voltage; determining a first flow rate based on the target adjustment coefficient and the first voltage; controlling water outlet of the water treatment device according to the first flow.

In this technical scheme, water treatment facilities includes instant heating type water dispenser, and instant heating type water dispenser includes water inlet pipeline, instant heating module, water outlet pipeline and water pump, and wherein, instant heating module connects water inlet pipeline and water outlet pipeline respectively, and the water pump setting is in water inlet pipeline side, pumps cold water to instant heating module through water inlet pipeline, heats the back to cold water through instant heating module, forms the hot water supply of constant flow, fixed temperature.

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

The flow of the water pump is generally calibrated by leaving a factory, and the pipeline connected with the water pump is fixed during calibration. Because the product designs are different, different water dispensers using the same water pump have different waterway designs, such as different structural layouts of internal pipelines. In actual products, the length, the number of elbows and the pipe diameter of the waterway pipeline and even the installation height of the water dispenser can influence the pump water flow of the 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 problems, the first voltage of the water pump is determined after the water outlet instruction is received. 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, whereas 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 may be reported to the control board of the water dispenser by the water pump by itself, thereby realizing accurate identification of the first voltage.

In other embodiments, a corresponding voltage detection module may be further provided, and the first voltage of the water pump is detected in real time through the voltage detection module.

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, namely a pipeline loss coefficient of a water pump in the instant heating type water dispenser, namely the difference between the standard pump water flow (namely rated pump water flow) and the actual pump water flow of the water pump in an ideal state, and according to the target adjustment coefficient, the actual pump water flow under the current pipeline structure of the water dispenser, namely the first flow, can be calculated when the water pump pumps water under the driving of the first voltage.

The water treatment device is controlled by the corrected first flow, such as the instant heating type water dispenser to perform water discharge and heating, so that the condition that the actual pump water flow of the water pump is inconsistent with the design pump water flow, the finally-caused water discharge temperature is inconsistent with the setting, or the water discharge quantity is inconsistent with the setting 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 accuracy of water outlet and the accuracy of temperature control are ensured, and the use experience of the instant heating water dispenser is improved.

In addition, the control method of the water treatment device in the technical scheme provided by the application can also have the following additional technical characteristics:

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

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

Because the design of the internal pipeline of the instant heating type water dispenser is different, the waterway length, the pipeline bending number and the pipe diameter are also different from the ideal state after the water pump is installed in the water treatment device, such as the instant heating type water dispenser, the theoretical pump water flow of the water pump can generate pipeline loss, and the first relation is the relation of the driving voltage of the water pump and the theoretical pump water flow (rated flow, namely second flow) under the condition of no pipeline loss when the water pump is accurately reflected in the ideal state, namely the water pump is only connected with an extreme pipeline (or not connected with the pipeline).

Therefore, according to the current real-time working voltage of the water pump, namely the first voltage, which is actually collected, and the prestored first relational expression, the pump water flow of the water pump in an ideal state, namely the second flow, 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 pipeline loss of the water pump in the instant heating type water dispenser, and through the target adjustment coefficient, namely compared with the difference between the standard pump water flow and the actual pump water flow of the water pump in an ideal state, the actual pump water flow under the current internal pipeline structure of the water dispenser, namely 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 instant heating type water dispenser to perform water discharge and heating, so that the phenomenon that the actual pump water flow of the water pump is inconsistent with the designed pump water flow due to the design of the internal pipeline of the water dispenser can be effectively avoided, and more accurate water discharge is realized.

In any of the above embodiments, the first relational expression is a relational expression of 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, namely the rated pump water flow of the water pump when the driving voltage of the water pump is the first voltage in an ideal state, is determined according to the first voltage, namely the collected real-time working voltage of the water pump and the first relation.

The first relation can be a relation which reflects the corresponding relation between different working voltages of the reference water pump and different rated pump water flows of the reference water pump. The reference water pump specifically refers to the water pump flow rate when the water pump is connected with an extreme pipeline only as the water pump arranged in the water treatment device, such as the instant heating type water dispenser, namely the standard water pump flow rate when the water pump with the same model and the same parameters as the water pump arranged in the current water treatment device is not influenced by the pipeline.

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

In the technical scheme, after the current real-time working voltage of the water pump, namely the first voltage is acquired, 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 relation can reflect the correspondence between the standard pumping capacity (rated pumping capacity) of the reference water pump, that is, the water pump not affected by the pipeline loss, and the actual pumping capacity of the water pump installed in the instant water dispenser under the influence of the internal pipeline of the instant water dispenser.

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

Therefore, the actual pump water flow of the water pump of the instant heating type water dispenser is compensated and regulated through the second relation, namely, the second flow of the water pump is regulated through the second relation, the actual flow of the water pump is obtained, namely, the first flow is obtained, the instant heating module and the water outlet of the water dispenser are precisely controlled through the regulated first flow, the accuracy of water yield 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 foregoing 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 the 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 flows

According to the technical scheme, when the instant heating type water dispenser leaves the factory, the first relation between the actual working voltage of the water pump and the rated pump water flow is determined according to the selected water pump and the set water channel and is prestored in the 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 can be determined under the current working voltage through the first relation, 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 are 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 the rated operating voltage of the reference water pump. It can be understood that the more the number of standard operating voltages that are taken by the experiment, the denser the distribution, the higher the experimental effect.

After N standard operating voltages are obtained, standard flow experiments, i.e. short-pole pipe experiments, are performed on the reference water pump according to the N standard operating voltages. Specifically, the reference water pump is connected to a pole short pipeline, wherein the pole short pipeline refers to a pipeline length which does not generate loss or other influence on the pump water flow of the water pump, and under the condition of connecting the pole short pipeline, the actual pump water flow of the water pump is identical to the rated pump water flow.

In the experimental process, the reference water pump is driven to pump water through N standard working voltages, and standard pump water flows of the water pump, namely rated pump water flows of the water pump, are collected through the flowmeter under the driving of each working voltage.

At N standard operating voltages including voltage Va ₁ Voltage Va ₂ … … Voltage Va _n For example, the corresponding first rated pump water flow includes flow Q _{Standard 1} Flow rate Q _{Standard 2} … … flow rate Q _{Standard n} Wherein each operating voltage corresponds to a standard flow rate.

According to Va ₁ 、Va ₂ ……Va _n And 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 relation of the rated pump water flow, namely, the relation function of the standard flow of the reference water pump and the voltage, is recorded as:

Q _{standard of} ＝f(V)，V＝Va ₁ 、Va ₂ ……Va _n ；

Wherein Q is _{Standard of} 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, so that the rated pump water flow is adjusted and corrected through the target adjusting coefficient, the pump water flow can be calculated more accurately through the instant heating type water dispenser, the accuracy of water flow calculation and temperature calculation is improved, and the water outlet effect is improved.

In any of the above solutions, before determining the target adjustment coefficient, the control method further includes: based on the first relation, determining M second rated pump water flows corresponding to M third voltages, wherein M is a positive integer; collecting M actual pump water flows of the water pump under M third voltages respectively, wherein the M actual pump water flows and the M second rated pump water flows are in one-to-one correspondence; determining M preset adjustment coefficients corresponding to each third voltage according to the ratio of the actual pump water flow to the second rated pump water flow corresponding to each M third voltages; and fitting according to the M third voltages and the M preset adjustment coefficients to obtain a second relation.

In the technical scheme, when the instant heating type water dispenser leaves the factory, a first relation between the actual working voltage of the water pump and rated pump water flow is prestored, 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 relation.

After the rated pump water flow is obtained, a target adjustment coefficient suitable for correcting the real-time pump water flow of the water pump is further determined through a second relation.

Specifically, the second relation can reflect the correspondence between the standard pumping capacity of the reference water pump, that is, the water pump not affected by the pipeline loss, and the actual pumping capacity of the water pump installed in the instant water dispenser under the influence of the internal pipeline of the instant water dispenser. The second flow of the water pump is regulated through the second relation, the actual flow of the water pump, namely the first flow, is obtained, the instant heating module and the water outlet of the water dispenser are precisely controlled through the regulated first flow, and the accuracy of water yield and the accuracy of temperature control are ensured.

Specifically, M standard operating voltages of the water pump currently installed in the instant heating type water dispenser, that is, the M third voltages, 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 that are taken by the experiment, the denser the distribution, the higher the experimental effect.

After obtaining the M standard working voltages (i.e., the third voltages), calculating rated pump water flows corresponding to the M standard working voltages respectively according to the first relational expression, and obtaining M second rated pump water flows corresponding to the M standard working voltages one by one.

After obtaining M second rated pump water flows, carrying out flow experiments on the whole machine of the instant heating type water dispenser, specifically, driving a water pump of the instant heating type water dispenser to work through M standard working voltages (third voltages) respectively, and collecting the actual water outlet flows of the instant heating type water dispenser under the driving of each third voltage through a flowmeter, wherein the obtained M actual water outlet flows, namely M actual pump water flows of the water pump in the instant heating type water dispenser, are in one-to-one correspondence with the M second rated pump water flows.

Here, a default adjustment system is definedNumber k=q _{Complete machine} ÷Q _{Standard of} ；

Wherein k is a preset adjustment coefficient, Q _{Complete machine} Is the actual pump water flow rate Q of a water pump in the instant heating type water dispenser _{Standard of} The water pump is the standard pump water flow, namely the rated pump water flow, of the same type of water pump when the extremely short pipeline is connected.

Let M third voltages be Vc ₁ 、Vc ₂ ……Vc _m The M second rated pump water flows include: q (Q) _{Complete machine 1} 、Q _{Whole machine 2} ……Q _{Complete machine m} Correspondingly, the M second rated pump water flows comprise: q (Q) _{Standard 1} 、Q _{Standard 2} ……Q _{Standard m} 。

Thus, defining the preset adjustment factor includes k ₁ 、k ₂ ……k _m And satisfies the following formula:

Wherein k is ₁ With Vc ₁ Is a group of data, k ₂ With Vc ₂ For a set of data … … k _m With Vc _m The coefficient k represents the influence of the whole water inlet and outlet pipeline of the instant heating type water dispenser on the flow of the 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 model under the same driving voltage.

After obtaining the above experimental data, k is determined ₁ 、k ₂ ……k _m With Vc ₁ 、Vc ₂ ……Vc _m Fitting to the corresponding functional relation: k=f (V) to obtain a second relational expression, and compensating and adjusting the actual pump water flow of the water pump of the instant heating type water dispenser by the second relational expression, namely adjusting the second flow of the water pump by the second relational expression to obtain the actual flow of the water pump, namely the first flow, and heating the instant heating type water dispenser by the adjusted first flowThe module and the water outlet are precisely controlled, the water outlet amount is ensured to be accurate, the temperature is controlled accurately, and the use experience of the instant heating type water dispenser is improved.

In any of the above embodiments, the number of the second relational expressions is M-1; fitting to obtain a second relation according to the M third voltages and the M preset adjustment coefficients, wherein the second relation comprises: and fitting according to the O-th third voltage in the M third voltages and the O-th adjustment coefficient in the M preset adjustment coefficients to obtain a second relation corresponding to the target voltage range, wherein the target voltage range is more than or equal to the O-1 th third voltage and less than the O-th third voltage, and O is a positive integer less than M.

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

Specifically, M-1 piecewise functions correspond to M-1 voltage ranges, respectively, the M-1 voltage ranges including: [ Vc ] ₁ ，Vc ₂ )、[Vc ₂ ，Vc ₃ )……[Vc _m-1 ，Vc _m ) For each voltage range, a piecewise function relation is set independently, specifically, the piecewise function includes:

k＝f ₂ (V)＝a ₂ ×V+b ₂ ，Vc ₂ ≤V＜Vc ₃ ；

……

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 。

wherein 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 water dispenser is acquired, the voltage range corresponding to the first voltage is firstly judged, so that a target relation is determined in the piecewise function, a target adjustment coefficient is obtained through calculation of the target relation, and according to the target adjustment coefficient, the actual pump water flow, namely the first flow, under the internal pipeline structure of the instant water dispenser can be calculated when the water pump pumps water under the driving of the first voltage.
