The invention provides a regulation and control method of an instant heating type heating assembly in a first aspect, which comprises the following steps: acquiring heating time required by increasing the outlet water temperature of the instant heating type heating assembly to a preset temperature value; acquiring a driving value of a liquid supply part of the instant heating type heating assembly; and determining a heating energy value of the instant heating assemblies according to the heating time, the comparison value and the driving value, wherein the instant heating assembly group comprises at least two instant heating assemblies.

The regulating and controlling method of the instant heating type heating assembly provided by the invention can calculate and update the heating capacity value of the instant heating type heating assembly in the using process of the instant heating type heating assembly, thereby ensuring that each instant heating assembly has an accurate heating capacity value, avoiding the errors and the influence brought by each component of the instant heating type heating assembly, even avoiding the abnormal heating capacity value caused by different using environments, ensuring that the instant heating assembly can accurately heat water flow to the specified temperature in the using process, and realizing the accurate control of water temperature.

In the using process of the instant heating assembly, the regulating and controlling method provided by the invention can obtain the driving value of the liquid supply part of the instant heating assembly, wherein the driving value is a parameter value for driving the water pump to work, and can be a current value or a voltage value. In addition, the regulating and controlling method can also obtain the outlet water temperature of the instant heating type heating assembly and obtain the heating time required by the outlet water temperature to increase the preset temperature value. And then, calculating the heating capacity value of the instant heating assembly according to the driving value of the liquid supply part of the instant heating assembly, the heating time required by the outlet water temperature of the instant heating assembly to increase the preset temperature value and the comparison value, so that the self-learning process of the heating capacity value of the instant heating assembly is realized, and the accuracy of the heating capacity value of the instant heating assembly is ensured.

Specifically, the tankless heating assembly includes a liquid supply component and a heating component. The heating capacity value of the instant heating component refers to: and the heating energy value is reflected by the maximum stable temperature rise generated by the instant heating type heating assembly under the drive of the fixed power supply voltage of the heating component and the fixed drive voltage of the liquid supply component. The concept of the heating power value described above will be understood by those skilled in the art.

Therefore, the regulating and controlling method of the instant heating assembly provided by the invention can calculate the heating capacity value of the instant heating assembly according to the heating time required by the outlet water temperature to increase the preset temperature value, the driving value of the liquid supply part of the instant heating assembly and the comparison value of the instant heating assembly group where the instant heating assembly is located, thereby realizing the self-learning of the instant heating assembly.

In some possible designs, the comparison value includes a standard heating time and a minimum heating time.

In this design, the parameter values include a standard heating time and a minimum heating time. That is, the heating capacity value of the instant heating assembly can be determined according to the temperature rise value of the instant heating assembly, the standard heating time and the minimum heating time. It is understood that the standard heating time is a parameter value related to the outlet water temperature and the inlet water temperature of the tankless heating assembly, and the minimum heating time is also a parameter value related to the outlet water temperature and the inlet water temperature of the tankless heating assembly. The water outlet temperature and the water inlet temperature of the instant heating type heating assembly also reflect the heating capacity value of the instant heating type heating assembly.

In some possible designs, the step of determining a heating power value of the tankless heating assembly based on the heating time, the comparison value, and the drive value includes: calculating a first difference between the standard heating time and the time-related value; calculating a second difference between the standard heating time and the minimum heating time; determining a heating capacity value according to the proportional relation between the first difference value and the second difference value; wherein the time-dependent value is determined from the heating time and the drive value.

In the design, in the process of determining the heating capacity value of the instant heating type heating assembly, firstly, a time correlation value is determined according to the heating time and the driving value; then, calculating a first difference between the standard heating time and the time correlation value and a second difference between the standard heating time and the minimum heating time; further, a heating energy value of the instant heating assembly is calculated according to a proportional relation between the first difference value and the second difference value. Specifically, a heating energy value of the instant heating assembly is determined according to a ratio of the first difference value to the second difference value.

Specifically, the time-related value is: the quotient of the square of the drive value and the mains voltage (220V) is multiplied by the heating time.

In some possible designs, the comparison value is pre-stored in the tankless heating assembly.

In this design, the parameter values may be preset within the instant heating assembly. Specifically, the heating element may be preset in the main control board of the instant heating assembly. That is, when determining the heating capacity value of the tankless heating assembly, the previously stored parameter value may be directly retrieved.

In particular, the process of storing the parameter values is already done during the design or manufacturing process of the instant heating assembly. Specifically, in the process of selecting the parameter value, the parameter value can be confirmed according to the tolerance combination of each component of the instant heating assembly.

In some possible designs, the comparison value is determined from a comparison value of one of the plurality of tankless heating assemblies.

In this design, the parameter value may be determined from a parameter value of one of the plurality of tankless heating assemblies. Specifically, in the process of producing the instant heating assemblies, a plurality of instant heating assemblies are produced. Therefore, the instant heating system can select one of the instant heating assemblies and select the relevant parameter of the instant heating assembly as the parameter value.

Particularly, the instant heating assembly can be in the same batch with the instant heating assembly of which the heating power value is to be calculated, or can be in a different batch with the instant heating assembly of which the heating power value is to be calculated.

In some possible designs, the comparison value is determined according to the heating power of the heating component of the tankless heating assembly and the liquid flow rate of the liquid supply component.

In the design, the parameter value according to which the instant heating assembly is determined in the process of determining the heating capacity value of the instant heating assembly is determined according to the heating power of the heating component of the instant heating assembly and the liquid flow of the water supply component of the instant heating assembly. Therefore, in the process of calculating the heating energy value, the heating power of the heating component and the liquid flow of the water supply component can be fully considered, so that the calculation result of the heating energy value is more accurate.

In some possible designs, the parameter values are determined by the following process: controlling the heating component to work at a nominal maximum power and the water supply component to work at a nominal minimum flow to obtain a maximum outlet water temperature; controlling the heating component to work at a nominal minimum power and the water supply component to work at a nominal maximum flow rate to obtain a minimum outlet water temperature; taking the difference between the minimum water outlet temperature and the minimum water inlet temperature as the minimum heating time; any time value between the minimum heating time and the maximum heating time is selected as the standard heating time.

In this design, each tankless heating assembly has a nominal power range and a nominal flow range. Under the condition that the inlet water temperature is the same, the instant heating type heating assembly works with different heating powers, and the outlet water temperature is different; correspondingly, under the condition that the water inlet temperature is the same, the instant heating type heating assembly works at different liquid flow rates, and the water outlet temperature is different.

The above-mentioned maximum temperature rise and standard heating time are therefore determined as follows:

firstly, controlling the heating component to work at a nominal maximum power, and simultaneously controlling the water supply component to work at a nominal minimum flow, and obtaining the maximum outlet water temperature of the instant heating component in the state; and then, controlling the heating component to work at a nominal minimum power, and simultaneously controlling the water supply component to work at a nominal maximum flow, and obtaining the minimum outlet water temperature of the instant heating type heating component in the state.

Thus, the difference between the minimum leaving water temperature and the entering water temperature is calculated and the difference is taken as the minimum heating time.

Thus, any time value between the minimum heating time and the maximum heating time is selected as the standard heating time.

In some possible designs, the time value is an average of the minimum heating time and the maximum heating time.

In this design, the time value may be an average of the minimum heating time and the maximum heating time. That is, in the calculation of the standard heating time, the average value of the minimum heating time and the maximum heating time is first calculated, and then the equilibrium value is calculated as the above-mentioned temperature rise standard value.

In some possible designs, the method for regulating the instantaneous heating assembly is characterized by further comprising: storing the heating energy value; and controlling the liquid supply component and/or the heating component of the instant heating type heating assembly to work according to the heating energy value.

In the design, after the heating capacity value is obtained through calculation, the calculated heating capacity is stored, so that the subsequent use of the instant heating type heating assembly is facilitated.

In addition, after the heating capacity value of the instant heating type heating assembly is obtained, the instant heating type heating assembly can be controlled to work according to the heating capacity value. Specifically, the operation of the water supply component or the heating component of the instant heating type heating assembly is controlled, and the simultaneous operation of the water supply component and the heating component can also be controlled.

In some possible designs, the step of obtaining a drive value for a liquid supply component of the tankless heating assembly includes: acquiring the water inlet temperature of the instant heating type heating assembly; acquiring the set water temperature of the instant heating type heating assembly; and determining a driving value according to the water inlet temperature, the set water temperature and the power grid voltage of the instant heating type heating assembly.

In the design, under different use scenes, the driving values of the water pumps are different, and the driving values of the water pumps are different, so that the different water outlet flows of the instant heating type heating assembly are influenced. For example, the water inlet temperature of the instant heating module, the set water outlet temperature of the instant heating module, and the voltage of the power grid connected to the instant heating module all affect the driving value of the water pump. Therefore, in the process of determining the driving value of the water pump, the outlet water temperature and the inlet water temperature of the instant heating type heating assembly are firstly obtained, the set outlet water temperature (namely the temperature set by the user) of the instant heating type heating assembly is obtained, and the power grid voltage connected with the instant heating assembly is obtained. And then, determining a driving value of the water pump according to the power grid voltage, the set water outlet temperature and the set water inlet temperature.

Therefore, the method determines the use scene of the instant heating type heating assembly through the power grid voltage, the set water outlet temperature and the set water inlet temperature, determines the driving value of the driving component in the use scene, and continuously calculates and determines the heating capacity value of the instant heating type heating assembly under the condition that the driving component works with the driving value so as to obtain the real and accurate heating capacity value of the instant heating assembly in the application scene.

In some possible designs, the method of modulating further comprises: determining the heating power of a heating component of the instant heating component according to the water inlet temperature, the set water temperature and the power grid voltage of the instant heating component; controlling the liquid supply part to work according to the driving value; and controlling the heating part to work according to the heating power.

In the design, under different use scenes, the driving value of the water pump is different, the heating power of the heating element is different, and the heating effect of the instant heating type heating assembly is different. For example, the water inlet temperature of the instant heating module, the set water outlet temperature of the instant heating module, and the voltage of the power grid connected to the instant heating module all affect the driving value of the water pump. Therefore, the invention can determine the heating power of the heating element according to the power grid voltage, the set water outlet temperature and the set water inlet temperature, and control the heating element to work according to the heating power.

Therefore, the method determines the use scene of the instant heating type heating assembly through the power grid voltage, the set water outlet temperature and the set water inlet temperature, determines the heating power of the heating element in the use scene, and continuously calculates and determines the heating capacity value of the instant heating type heating assembly under the condition that the heating element works according to the heating power so as to obtain the real and accurate heating capacity value of the instant heating assembly in the application scene.

In some possible designs, the step of determining the heating time required for the water temperature to rise to the preset temperature value comprises: starting timing when the outlet water temperature is a first temperature value; stopping timing when the water outlet temperature is a second temperature value to obtain heating time; the second temperature value is greater than the first temperature value, and the preset temperature value is a difference value between the second temperature value and the first temperature value.

In the design, in the operation process of the instant heating assembly, when the outlet water temperature of the instant heating assembly is detected to be a first temperature value, timing is started; then, the instant heating type heating assembly continuously operates; and stopping timing when the outlet water temperature of the instant heating type heating assembly is detected to reach the second temperature value. Therefore, the heating time required for heating the outlet water temperature of the instant heating type heating assembly from the first temperature value to the second temperature value can be obtained. The difference between the second temperature value and the first temperature value is the preset temperature value.

It should be noted here that the second temperature value is greater than the first temperature value, and the second temperature value is less than the set outlet water temperature of the instant heating assembly. That is, the present invention detects the temperature of water during the temperature rise of the liquid (i.e. the temperature rise stage), and obtains the heating time required for the temperature of the outlet water to rise to the preset temperature value.

In some possible designs, the method of modulating further comprises: and determining the heating capacity value of the instant heating type heating assembly at set time intervals, and updating the heating capacity value.

In the design, after the instant heating assembly is used for a period of time (for example, after the instant heating assembly is used for several months or years), a series of product conditions such as pipeline scaling, water pump rotating speed attenuation, pipeline aging and the like can occur to the instant heating assembly. Therefore, in the using process of the instant heating assembly, the heating capacity value of the instant heating assembly is not fixed and is generally gradually reduced. Therefore, the driving value of the water pump in the instant heating type heating assembly and the temperature rise value of the outlet water temperature are obtained again every set time (such as months or years); and then, according to the driving value and the temperature rise value of the instant heating assembly and the comparison value of the instant heating assembly group where the instant heating assembly is located, recalculating the heating capacity value of the instant heating assembly, and updating the previously stored heating capacity value to ensure that the heating capacity value is matched with the service time of the instant heating assembly, so that the heating capacity value of the instant heating assembly is more accurate.

The regulating and controlling device of the instant heating type heating assembly comprises an obtaining unit and a control unit. The acquisition unit can acquire a driving value of a liquid supply component of the instant heating type heating assembly, wherein the driving value is a parameter value for driving the water pump to work, and can be a current value or a voltage value. In addition, the regulating and controlling method can also obtain the outlet water temperature of the instant heating type heating assembly and obtain the heating time required by the outlet water temperature to increase the preset temperature value. Then, the control unit calculates the heating capacity value of the instant heating assembly according to the driving value of the liquid supply part of the instant heating assembly, the heating time required by the outlet water temperature of the instant heating assembly to increase the preset temperature value and the comparison value, so that the self-learning process of the heating capacity value of the instant heating assembly is realized, and meanwhile, the accuracy of the heating capacity value of the instant heating assembly is ensured.

The second embodiment of the invention provides a method for regulating and controlling an instant heating type heating assembly, which is based on the first embodiment and further comprises the following steps:

the parameter values include a standard heating time and a minimum heating time. That is, the heating capacity value of the instant heating assembly can be determined according to the temperature rise value of the instant heating assembly, the standard heating time and the minimum heating time.

It is understood that the standard heating time is a parameter value related to the outlet water temperature and the inlet water temperature of the tankless heating assembly, and the minimum heating time is also a parameter value related to the outlet water temperature and the inlet water temperature of the tankless heating assembly.

Specifically, in the process of producing the instant heating assemblies, a plurality of instant heating assemblies are produced. Therefore, the instant heating system can select one of the instant heating assemblies and select the relevant parameter of the instant heating assembly as the parameter value.

The fifth embodiment of the invention provides a method for regulating and controlling an instant heating type heating assembly, which is based on the second embodiment and further comprises the following steps:

the parameter value according to in the process of determining the heating capacity value of the instant heating type heating assembly is determined according to the heating power of the heating component of the instant heating type heating assembly and the liquid flow of the water supply component of the instant heating type heating assembly. Therefore, in the process of calculating the heating energy value, the heating power of the heating component and the liquid flow of the water supply component can be fully considered, so that the calculation result of the heating energy value is more accurate.

Further in this embodiment, each tankless heating assembly has a nominal power range and a nominal flow range. Under the condition that the inlet water temperature is the same, the instant heating type heating assembly works with different heating powers, and the outlet water temperature is different; correspondingly, under the condition that the water inlet temperature is the same, the instant heating type heating assembly works at different liquid flow rates, and the water outlet temperature is different.

Specifically, the time value may be an average of the minimum heating time and the maximum heating time. That is, in the calculation of the standard heating time, the average value of the minimum heating time and the maximum heating time is first calculated, and then the equilibrium value is calculated as the above-mentioned temperature rise standard value.

Of course, the time value may not be an average value of the minimum heating time and the maximum heating time.

A sixth embodiment of the present invention provides a method for regulating and controlling an instant heating component, and based on the first embodiment, the method further comprises:

and after the heating capacity value is obtained through calculation, the heating capacity obtained through calculation is stored so as to facilitate the use of the subsequent instant heating type heating assembly.

under the different use scenes, the drive value of water pump can be different, and the drive value of water pump is different, can influence instant heating type heating element's play water flow different. For example, the water inlet temperature of the instant heating module, the set water outlet temperature of the instant heating module, and the voltage of the power grid connected to the instant heating module all affect the driving value of the water pump.

In the process of determining the drive value of the water pump, the outlet water temperature and the inlet water temperature of the instant heating type heating assembly are firstly obtained, the set outlet water temperature (i.e. the temperature desired by the user) of the instant heating type heating assembly is obtained, and the power grid voltage connected with the instant heating assembly is obtained. And then, determining a driving value of the water pump according to the power grid voltage, the set water outlet temperature and the set water inlet temperature.

An eighth embodiment of the present invention provides a method for regulating and controlling an instant heating component, and further, on the basis of the third embodiment:

under the different use scenes, the drive value of water pump can be different, and the heating power of heating member is different, can lead to instant heating type heating element's heating effect different. For example, the water inlet temperature of the instant heating module, the set water outlet temperature of the instant heating module, and the voltage of the power grid connected to the instant heating module all affect the driving value of the water pump.

Therefore, the embodiment determines the heating power of the heating element according to the power grid voltage, the set water outlet temperature and the set water inlet temperature, and controls the heating element to work according to the heating power.

starting timing when the detected outlet water temperature is a first temperature value; then, the instant heating type heating assembly continuously operates; and stopping timing when the outlet water temperature reaches the second temperature value. Therefore, the heating time required by the temperature rise of the outlet water of the instant heating type heating assembly from the first temperature value to the second temperature value can be obtained. And the difference value obtained by subtracting the first temperature value from the second temperature value is the preset temperature value.

It should be noted here that the second temperature value is greater than the first temperature value, and the second temperature value is less than the set outlet water temperature of the tankless heating assembly. That is, the present invention detects the temperature of water during the temperature rise of liquid (i.e. temperature rise stage), and obtains the heating time required for the temperature of the outlet water to rise to the preset temperature value.
