In one possible design, the parameter values include a temperature rise criterion value and a temperature rise maximum value.

The parameter values comprise that the standard temperature rise value is the maximum temperature rise value. Namely, the heating capacity value of the heating device can be determined and obtained according to the temperature rise value of the instant heating type heating device, the temperature rise standard value and the temperature rise maximum value. It is understood that the standard temperature rise value is a parameter value related to the outlet water temperature and the inlet water temperature of the instantaneous heating device, and the maximum temperature rise value is a parameter value related to the outlet water temperature and the inlet water temperature of the instantaneous heating device. The water outlet temperature and the water inlet temperature of the instant heating type heating device also reflect the heating capacity value of the instant heating type heating device.

In one possible design, the step of determining the heating capacity value of the instantaneous heating device according to the temperature rise value, the driving value and the parameter value comprises: calculating a first difference value between the temperature rise correlation value and the temperature rise standard value; calculating a second difference value between the maximum temperature rise value and the standard temperature rise value; determining a heating capacity value according to the proportional relation between the first difference value and the second difference value; wherein the temperature rise correlation value is determined according to the temperature rise value and the driving value.

In the design, when the heating energy value of the instant heating device is measured, a temperature rise correlation value is determined according to a temperature rise value and a driving value; then, calculating a first difference value between the temperature rise correlation value and the temperature rise standard value and a second difference value between the maximum temperature rise value and the temperature rise standard value; thus, the heating capacity value can be determined according to the proportional relation between the first difference value and the second difference value. In particular, the heating power value may be determined by a ratio of the first difference to the second difference.

Specifically, the temperature rise correlation value is equal to: the quotient of the square of the mains voltage (220V) and the square of the drive value is multiplied by the temperature rise value.

Specifically, the driving value, the temperature rise value and the temperature rise standard value can be taken as the maximum temperature rise value into a preset formula, and then the heating energy value is obtained through formula calculation.

Wherein the predetermined formula is M ═ f (U, Δ T)_{Maximum of}，△T_{Standard of merit}) (ii) a Wherein M is the heating capacity value of the instant heating type heating device, U is the driving value of the water pump, Delta T is the temperature rise value of the instant heating type heating device, and Delta T_{Maximum of}For maximum temperature rise, Δ T_{Standard of merit}And is a standard value of temperature rise.

More specifically, the preset formula is

Wherein M is the heating capacity value of the instant heating type heating device, U is the driving value of the water pump, Delta T is the temperature rise value of the instant heating type heating device, and Delta T_{Maximum of}For maximum temperature rise, Δ T_{Standard of merit}And a and b are constants for temperature rise standard values. It should be noted here that a and b are selected in the normalization process, so that those skilled in the art can select them according to their needs, and will also understand that those skilled in the art can also select them.

In one possible design, the parameter values are preset in the tankless heating device.

In this design, the parameter values may be preset within the instant heating device. Specifically, the heating device may be preset in the main control board of the instant heating device. That is, when determining the heating capacity value of the tankless heating device, 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 device. 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 type heating device.

In one possible design, the parameter value is determined based on a parameter value of one of the plurality of tankless heating devices.

In this design, the parameter value may be determined from a parameter value of one of the plurality of tankless heating devices. Specifically, in the process of preparing the instant heating device, a plurality of instant heating devices are manufactured. Therefore, the instant heating system can select one of the instant heating devices as a target instant heating device, and select the relevant parameters of the target instant heating device as the parameter values. In particular, the target instantaneous heating device may be in the same batch as the instantaneous heating device for which the heating power value is to be calculated, or may be in a different batch from the instantaneous heating device for which the heating power value is to be calculated.

In one possible design, the parameter value is determined according to the heating power of the heating pipe of the instant heating device and the liquid flow of the water pump.

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

In one possible design, the parameter values are determined as follows: based on that the heating pipe works at the nominal maximum power, the water pump works at the nominal minimum flow and the maximum water outlet temperature; controlling the heating pipe to work at a nominal minimum power and the water pump to work at a nominal maximum flow rate to obtain a minimum outlet water temperature; taking the difference between the maximum water outlet temperature and the maximum water inlet temperature as the maximum temperature rise; selecting any temperature value between the maximum water outlet temperature and the minimum water outlet temperature; the difference between the temperature value and the inlet water temperature is used as the standard temperature rise value.

In this design, each tankless heating arrangement 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 device works with different heating powers, and the outlet water temperature is different; correspondingly, under the condition that the inlet water temperature is the same, the instant heating type heating device works at different liquid flow rates, and the outlet water temperature is different.

Therefore, the process of determining the maximum temperature rise value and the standard temperature rise value is as follows:

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

Thus, the difference between the maximum outlet water temperature and the inlet water temperature is calculated, and the difference is taken as the maximum temperature rise.

Thus, any temperature value between the maximum water outlet temperature and the minimum water outlet temperature is selected, the difference between the temperature value and the water inlet temperature is calculated, and the difference value is used as the standard temperature rise value.

In one possible design, the temperature value is an average of the maximum leaving water temperature and the minimum leaving water temperature.

In this design, the temperature value is the average of the maximum leaving water temperature and the minimum leaving water temperature. That is, in the process of calculating the temperature rise standard value, the average value of the maximum outlet water temperature and the minimum outlet water temperature is calculated first, then the difference between the average value and the inlet water temperature is calculated, and the difference value is used as the temperature rise standard value.

In one possible design, the method for regulating the instantaneous heating device further includes: storing the heating energy value; and controlling the operation of a water pump and/or a heating pipe of the instant heating type heating device 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 instant heating type heating device can be conveniently used.

In addition, after the heating capacity value of the instant heating type heating device is obtained, the instant heating type heating device can be controlled to work according to the heating capacity value. Specifically, the water pump or the heating pipe of the instant heating type heating device is controlled to work, and the water pump and the heating pipe can also be controlled to work simultaneously.

In one possible design, the step of obtaining a driving value of a water pump of the instantaneous heating device includes: acquiring a target outlet water temperature of the instant heating type heating device; and determining a driving value according to the inlet water temperature, the target outlet water temperature and the driving voltage value connected with the instant heating type heating device.

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 device are influenced. For example, the inlet water temperature of the instantaneous heating device, the set outlet water temperature of the instantaneous heating device, and the grid voltage to which the instantaneous heating device is connected 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 device are firstly obtained, the set outlet water temperature (namely the temperature set by the user) of the instant heating type heating device is obtained, and the power grid voltage connected with the instant heating type heating device 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 invention determines the use scene of the instant heating type heating device 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 device 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 type heating device in the application scene.

In one possible design, the instantaneous heating device further includes a heating pipe, and the control method further includes: determining the heating power of the heating pipe according to the water inlet temperature, the target water outlet temperature and the driving voltage value connected with the instant heating type heating device; controlling the water pump to work according to the driving value; and controlling the heating pipe to work according to the heating power.

In this design, the tankless heating arrangement further comprises a heating tube for heating the liquid. Under the different use scenes, the drive value of the water pump can be different, the heating power of the heating pipe is different, and the heating effect of the instant heating type heating device can be influenced to be different. For example, the inlet water temperature of the instantaneous heating device, the set outlet water temperature of the instantaneous heating device, and the grid voltage to which the instantaneous heating device is connected all affect the driving value of the water pump. Therefore, the heating power of the heating pipe is determined according to the power grid voltage, the set water outlet temperature and the set water inlet temperature, and the heating pipe is controlled to work according to the heating power.

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

In a possible design, before the step of obtaining the inlet water temperature and the outlet water temperature of the instant heating type heating device, the method further includes: judging whether the variation of the outlet water temperature is smaller than or equal to a variation threshold value; and determining the difference between the water temperature and the inlet water temperature under the condition that the variation of the outlet water temperature is smaller than or equal to the variation threshold.

In the design, the working time of the instant heating type heating device can be divided into two stages, wherein the first stage is a temperature rise stage, and the outlet water temperature of the instant heating type heating device continuously rises; the second stage is a stable water outlet stage, wherein the water outlet temperature of the instant heating type heating device is within a stable interval range.

Particularly, before detecting the water inlet temperature of the instant heating type heating device and the water outlet temperature of the instant heating type heating device, the method firstly judges whether the instant heating device is in a temperature water outlet stage, and only starts to detect the water inlet temperature of the instant heating device and the water outlet temperature of the instant heating device when the instant heating device is in a stable water outlet stage. Therefore, the temperature rise value obtained in the subsequent extreme stage is the temperature rise value of the instant heating device in the stable water outlet stage, and the finally obtained heating capacity value in the extreme stage is more accurate.

Specifically, in the process of determining whether the instantaneous heating device is in the temperature water outlet stage, the variation of the water outlet temperature can be detected, and it is determined whether the variation is smaller than the variation threshold or equal to the variation threshold. If the variation of the outlet water temperature is smaller than the variation threshold or equal to the variation threshold, it indicates that the outlet water temperature of the instant heating type heating device is already stable, that is, the instant heating type heating device is in the stable outlet water stage. Specifically, the variation threshold may be designed according to actual situations, and is generally small.

In one possible design, the method of regulating further comprises: and determining the heating capacity value of the instant heating type heating device every set time length, and updating the heating capacity value.

In the design, after the instant heating device is used for a period of time (for example, after the instant heating device 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 in the instant heating device. Therefore, in the using process of the instant heating device, the heating capacity value of the instant heating device is not constant and generally gradually decreases.

Therefore, the driving value of the water pump in the instant heating device 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 device and the parameter value of the instant heating device group where the instant heating device is located, recalculating the heating capacity value of the instant heating device, 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 device, so that the heating capacity value of the instant heating device is more accurate.

In one possible design, the method of regulating further comprises: judging whether a regulation instruction is received; and determining the heating capacity value of the instant heating type heating device based on the received regulation and control instruction, and updating the heating capacity value.

In the design, during daily use of the instant heating device, a user can automatically control the instant heating device to perform self-learning of the heating capacity value. Specifically, when the user wants to update the heating capacity value of the instant heating type heating device, a regulation and control instruction can be input. After the instant heating device receives the regulating and controlling instruction, or recalculating and determining the heating capacity value of the instant heating device (the specific calculation and determination process is not repeatedly discussed herein); and then, the calculated heating capacity value is stored, and the previously stored heating capacity value is updated to ensure that the heating capacity value is matched with the service time of the instant heating type heating device, so that the heating capacity value of the instant heating type heating device is more accurate.

The second aspect of the present invention provides a regulating and controlling device for an instant heating type heating device, comprising: the system comprises an acquisition unit, a control unit and a control unit, wherein the acquisition unit is used for acquiring a driving value of a water pump of the instant heating type heating device and acquiring the water inlet temperature and the water outlet temperature of the instant heating type heating device; and the calculation unit is used for determining the difference value between the water temperature and the inlet water temperature, taking the difference value as the temperature rise value of the instant heating type heating device, and determining the heating energy value of the instant heating type heating device according to the temperature rise value, the parameter value and the driving value.

The regulating and controlling device of the instant heating type heating device comprises an obtaining unit and a control unit. The acquisition unit can acquire a driving value of the water pump of the instant heating device in the using process of the instant heating device, wherein the driving value is a parameter for driving the water pump to work and can be a current value or a voltage value. In addition, the acquiring unit can also acquire the inlet water temperature of the instant heating type heating device and the outlet water temperature of the instant heating type heating device respectively, calculate the difference value between the water temperature and the inlet water temperature, and take the difference value as the temperature rise value of the instant heating type heating device. And then, the control unit calculates the heating capacity value of the instant heating type heating device according to the driving value of the water pump of the instant heating type heating device, the temperature rise value and the parameter value of the instant heating type heating device, so that the self-learning process of the heating capacity value of the instant heating type heating device is realized, and meanwhile, the accuracy of the heating capacity value of the instant heating type heating device is ensured.

Therefore, the heating power of the heating pipe is determined according to the power grid voltage, the set water outlet temperature and the set water inlet temperature, and the heating pipe is controlled to work according to the heating power.
