Description

[0001] This application is a divisional application of a Chinese patent application with an application date of August 24, 2021, an application number of "202110976367.7", and an invention title of "Instant Heating Device and Its Control Method, Control Device, Water Treatment Device and Medium". Technical Field

[0002] The present invention relates to the field of instant heating technology, and in particular, to an instant heating device and its control method, control device, water treatment device and medium. Background Art

[0003] Instant heating products have the advantages of energy saving, small volume, low cost, etc., and are becoming more and more popular in daily life. However, in actual products, due to the limitation of production process level, the water flow speed tolerance of the water pump under the same driving voltage is ±20%, and after the user uses the product for several months or years, there may be a further change in the attenuation of the water pump speed. For the quantitative water output module of instant heating products, because the control main board cannot know the corresponding relationship between the driving value and the water flow speed of each machine, the control software can only use the default driving value - water flow speed curve to calculate the water output. However, because the tolerance of the water pump is too large, the characteristic curve of the water pump of each actual machine may deviate greatly from the default curve, resulting in inaccurate quantitative water output accuracy of the water dispenser. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art.

[0005] To this end, a first aspect of the present invention proposes a control method for an instant heating device.

[0006] A second aspect of the present invention proposes a control device for an instant heating device.

[0007] A third aspect of the present invention proposes an instant heating device.

[0008] A fourth aspect of the present invention proposes a water treatment device.

[0009] A fifth aspect of the present invention proposes a readable storage medium.

[0010] In view of this, according to one aspect of the present invention, a control method for an instant heating device is proposed. The instant heating device includes a water pump, and the control method includes: obtaining the characteristic value of the instant heating device; determining the second corresponding relationship between the driving value and the water flow speed of the water pump according to the characteristic value and the first corresponding relationship between the water flow speed in the water pump; and determining the water output of the water pump at any moment according to the second corresponding relationship.

[0011] The control method of the instant heating device provided by the present invention is used for an instant heating device, wherein the instant heating device includes a water pump. By obtaining the characteristic value of the instant heating device and according to the first corresponding relationship between the characteristic value and the water flow rate of the water pump, the second corresponding relationship between the driving value of the water pump and the water flow rate can be determined. After obtaining the second corresponding relationship, the instantaneous flow rate of the water pump at the current moment can be obtained through the second corresponding relationship, so that the water output at each moment during the water outlet process of the water pump can be determined. This avoids using the default corresponding relationship between the driving value of the water pump and the water flow rate in the related art to calculate the water output, thereby effectively improving the accuracy of quantitative water output.

[0012] It should be noted here that the instant heating device includes a heating component, and the characteristic value refers to: the heating capacity value reflected by the maximum stable temperature rise that different instant heating devices can achieve under the same power of the heating component and the same driving value of the water pump. Those skilled in the art can understand the concept of the above heating capacity value. Therefore, through the first corresponding relationship between the characteristic value and the water flow rate in the water pump, the actual water flow rate of the water pump under a fixed driving value can be determined, so that the second corresponding relationship between the driving value of the water pump and the water flow rate can be accurately determined, and further the water flow rate at each moment during the water outlet process can be accurately calculated, obtaining a more accurate quantitative water output accuracy.

[0013] Among them, the driving value of the water pump can be either voltage or current. The instant heating device can be an instant heating module with an instant heating function, or a device carrying the instant heating module, such as a water dispenser, a water heater, etc.

[0014] Through the control method of the instant heating device provided by the present invention, the characteristic values of different machines can be obtained. According to the first corresponding relationship between the characteristic value and the water flow rate, the second corresponding relationship between the driving value of the water pump and the water flow rate of different machines can be obtained. After obtaining the second corresponding relationship, the water flow rate at each moment during the water outlet process can be accurately calculated through the second corresponding relationship, so as to obtain a more accurate quantitative water output accuracy.

[0015] According to the above control method of the instant heating device of the present invention, it may also have the following technical features:

[0016] In the above technical solution, the control method of the instant heating device further includes: comparing the water output with a preset water output volume to determine whether to stop the water output.

[0017] In this technical solution, through the second corresponding relationship between the driving value of the water pump and the water flow velocity, the water flow velocity at each moment during the water outlet process of the water pump can be accurately obtained, thereby improving the quantitative water outlet accuracy. According to the water flow velocity, the volume of water that has flowed out of the water pump at the current moment, that is, the water output, can be calculated. By comparing the water output with the preset water output volume, it is determined whether to stop the water outlet, and the quantitative water outlet requirement can be achieved. Through the technical solution of the present invention, the quantitative water outlet accuracy can be effectively improved, and the quantitative water outlet effect can be improved.

[0018] Among them, the preset water output volume is the target water output volume set by the user.

[0019] In any of the above technical solutions, the step of determining whether to stop the water outlet specifically includes: stopping the water outlet based on the water output being equal to the preset water output volume.

[0020] In this technical solution, by judging whether the water output of the water pump has reached the preset water output volume, when the water output reaches the preset water output volume, the water outlet is stopped, thereby completing the quantitative water outlet.

[0021] In any of the above technical solutions, the step of determining the water output of the water pump at any moment according to the second corresponding relationship specifically includes: based on the start of water outlet of the water pump, obtaining the first driving value of the water pump and recording the water outlet time; determining the first water flow velocity corresponding to the first driving value according to the second corresponding relationship; and determining the water output according to the first water flow velocity and the water outlet time.

[0022] In this technical solution, a further limitation is made on determining the water output of the water pump at any moment according to the second corresponding relationship. When the water pump starts to discharge water, obtain the first driving value of the water pump, that is, the current driving value, and record the water discharge time. Through the second corresponding relationship between the driving value of the water pump and the water flow velocity, the water flow velocity corresponding to the current driving value can be calculated in real time. Combining with the water discharge time, the total volume of water that has flowed out, that is, the water output of the water pump, can be counted. Through the technical solution of the present invention, the water output can be accurately calculated, ensuring the quantitative water outlet effect.

[0023] It should be noted here that the first driving value is the driving value given by the main board to the water pump, so it is known. In addition, it should also be noted that the first driving value is the current driving value of the water pump. To ensure the water outlet effect, the first driving value is variable. Therefore, the corresponding water flow velocity is also changing.

[0024] In any of the above technical solutions, the step of determining the second corresponding relationship between the driving value and the water flow velocity of the water pump according to the first corresponding relationship between the characteristic value and the water flow velocity in the water pump specifically includes: determining different second water flow velocities of the water pump under different second driving values according to the characteristic value and the first corresponding relationship; and determining the second corresponding relationship between the driving value and the water flow velocity of the water pump according to the different second water flow velocities and different second driving values.

[0025] In this technical solution, it is defined that, according to the first correspondence between the characteristic value and the water flow velocity in the water pump, the second correspondence between the driving value of the water pump and the water flow velocity is determined. According to the characteristic value and the first correspondence, different second water flow velocities of the water pump driven by different second driving values can be obtained, that is, different water flow velocities of the water pump driven by different fixed driving values. Thus, multiple sets of data of the driving value and the water flow velocity are obtained, and then the second correspondence between the driving value and the water flow velocity of the water pump is determined based on these data. Through the technical solution of the present invention, the second correspondence between the driving value and the water flow velocity of the water pump can be obtained through the machine characteristic value and the first correspondence between the characteristic value and the water flow velocity of the water pump, and the software can accurately calculate the water flow velocity at each moment during the water outlet process through the second correspondence, so as to obtain a more accurate quantitative water outlet accuracy.

[0026] In any of the above technical solutions, the step of obtaining the characteristic value of the instant heating device specifically includes: in response to the quantitative water outlet instruction, obtaining the characteristic value of the instant heating device.

[0027] In this technical solution, it is defined to obtain the characteristic value of the instant heating device. When receiving the quantitative water outlet instruction, in response to the quantitative water outlet instruction, the characteristic value of the instant heating device is obtained. Further, based on the first correspondence between the characteristic value and the water flow velocity in the water pump, the second correspondence between the driving value of the water pump and the water flow velocity is determined. After obtaining the second correspondence, the water flow velocity at each moment during the water outlet process can be accurately calculated through the second correspondence, so as to obtain a more accurate quantitative water outlet accuracy.

[0028] In any of the above technical solutions, it further includes: determining a preset water outlet volume according to the quantitative water outlet instruction.

[0029] In this technical solution, when receiving the quantitative water outlet instruction, the preset water outlet volume can be determined according to the quantitative water outlet instruction. The preset water outlet volume is the target water output set by the user.

[0030] In any of the above technical solutions, before the step of obtaining the characteristic value of the instant heating device, it further includes: storing the characteristic value of the instant heating device.

[0031] In this technical solution, when the instant heating device passes the production line in the factory or is used at the user end, the characteristic value of the machine can be obtained by fixing the power of the heating component and the driving value of the water pump. By storing the characteristic value of the instant heating device, the characteristic value will be written into the EEPROM of the control main board and will not be lost when the power is off, so as to ensure the stability of the quantitative water outlet of the machine. Of course, it can also be stored in other memories, such as ROM, RAM, etc. In addition, when the user has a quantitative water outlet requirement, the software can directly obtain the characteristic value of the machine without executing the relevant program for obtaining the characteristic value of the machine again, which helps to quickly respond to the user's water outlet requirement.

[0032] In any of the above technical solutions, the first corresponding relationship includes any one or a combination of the following: a first relationship curve, a first relationship function, and a first relationship table; the second corresponding relationship includes any one or a combination of the following: a second relationship curve, a second relationship function, and a second relationship table.

[0033] In this technical solution, the first corresponding relationship between the local characteristic value and the water flow velocity in the water pump includes any one or a combination of a first relationship curve, a first relationship function, and a first relationship table, but is not limited thereto. That is, the water flow velocity corresponding to the local characteristic value can be obtained through various methods such as the curve corresponding method, the function calculation method, and the table lookup method. Similarly, the second corresponding relationship between the driving value of the water pump and the water flow velocity includes any one or a combination of a second relationship curve, a second relationship function, and a second relationship table, but is not limited thereto. That is, the water flow velocity corresponding to the current driving value of the water pump can be obtained through various methods such as the curve corresponding method, the function calculation method, and the table lookup method. This can adapt to various working scenarios, facilitate better control of the outlet water temperature and volume, and improve the outlet water effect.

[0034] In any of the above technical solutions, the first relationship function is determined according to the first relationship curve; the second relationship function is determined according to the second relationship curve.

[0035] In this technical solution, the first relationship function between the characteristic value and the water flow velocity in the water pump can be obtained through the first relationship curve. Similarly, the second relationship function between the driving value of the water pump and the water flow velocity can be obtained according to the second relationship curve.

[0036] According to the second aspect of the present invention, a control device for an instant heating device is proposed. The instant heating device includes a water pump, and the control device includes: an acquisition unit for acquiring the characteristic value of the instant heating device; a calculation unit for determining the second corresponding relationship between the driving value of the water pump and the water flow velocity according to the first corresponding relationship between the characteristic value and the water flow velocity in the water pump; and the calculation unit is further configured to determine the water output of the water pump at any moment according to the second corresponding relationship.

[0037] For the control device of the instant heating device provided by the present invention, the instant heating device includes a water pump. The characteristic value of the instant heating device is acquired through the acquisition unit, and the second corresponding relationship between the driving value of the water pump and the water flow velocity can be determined by the calculation unit according to the first corresponding relationship between the characteristic value and the water flow velocity in the water pump. After obtaining the second corresponding relationship, the calculation unit can obtain the instantaneous flow velocity of the water pump at the current moment through the second corresponding relationship, so as to be able to determine the water output of the water pump at any moment during the water output process. This avoids using the default corresponding relationship between the driving value of the water pump and the water flow velocity in the related art to calculate the water output, thereby effectively improving the quantitative water output accuracy.

[0038] It should be noted here that the instant heating device includes a heating component, and the characteristic value refers to: the heating capacity value reflected by the maximum stable temperature rise that different instant heating devices can achieve under the same power of the heating component and the same driving value of the water pump. Those skilled in the art can understand the concept of the above-mentioned heating capacity value. Therefore, through the first correspondence between the characteristic value and the water flow velocity in the water pump, the actual water flow velocity of the water pump under a fixed driving value can be determined, so that the second correspondence between the driving value and the water flow velocity of the water pump can be accurately determined, and then the water flow velocity at each moment during the water outlet process can be accurately calculated, obtaining a more accurate quantitative water outlet accuracy.

According to the first correspondence between the characteristic value and the water flow velocity in the water pump, the second correspondence between the water pump driving value and the water flow velocity of different machines can be obtained. After obtaining this second correspondence, the water flow velocity at each moment during the water outlet process can be accurately calculated through this correspondence, so as to obtain a more accurate quantitative water outlet accuracy.

[0064] In order to more clearly understand the above objects, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0065] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the limitations of the specific embodiments disclosed below.

[0066] Next, refer to Figures 1 to 10 to describe an instant heating device and its control method, control device, water treatment device, and medium provided according to some embodiments of the present invention.

[0067] In an embodiment of the present invention, a control method for an instant heating device is proposed. As Figure 1 shown, the control method includes:

[0068] Step 102, obtaining characteristic values of the instant heating device;

[0069] Step 104, determining a second correspondence between the driving value of the water pump and the water flow rate according to the first correspondence between the characteristic values and the water flow rate in the water pump;

[0070] Step 106, determining the water output of the water pump at any moment according to the second correspondence.

[0071] The control method for the instant heating device provided in this embodiment is used for the instant heating device, where the instant heating device includes a water pump. By obtaining the characteristic values of the instant heating device and according to the first correspondence between the characteristic values - the water flow rate of the water pump, the second correspondence between the driving value of the water pump - the water flow rate can be determined. After obtaining the second correspondence, the instantaneous flow rate of the water pump at the current moment can be obtained through the second correspondence, so that the water output of the water pump at each moment during the water output process can be determined. Avoiding using the default correspondence between the driving value of the water pump and the water flow rate in the related art to calculate the water output, thereby effectively improving the quantitative water output accuracy.

[0072] It should be noted here that the instant heating device further includes a heating component, and the characteristic value refers to: the heating capacity value reflected by the maximum stable temperature rise that different instant heating devices can achieve under the same power of the heating component and the same driving value of the water pump. Those skilled in the art can understand the concept of the above heating capacity value.

[0073] Therefore, through the correspondence between the characteristic value and the water flow velocity in the water pump, the actual water flow velocity of the water pump under a fixed driving value can be determined, so that the correspondence between the driving value and the water flow velocity of the water pump can be accurately determined. Furthermore, the water flow velocity at each moment during the water outlet process can be accurately calculated, and a more accurate quantitative water outlet accuracy can be obtained.

[0074] Among them, the driving value of the water pump can be either voltage or current. The instant heating device can be an instant heating module with an instant heating function, or a device carrying the instant heating module, such as a water dispenser, a water heater, etc.

[0075] Through the control method of the instant heating device provided in this embodiment, the characteristic values of different machines can be obtained. According to the correspondence between the characteristic value - water flow velocity, the correspondence between the driving value - water flow velocity of the water pumps of different machines, that is, the second correspondence, can be obtained. The water flow velocity at each moment during the water outlet process can be accurately calculated through the second correspondence, so as to obtain a more accurate quantitative water outlet accuracy.

[0076] In an embodiment of the present invention, a control method for an instant heating device is proposed, as Figure 2 shown. The control method includes:

[0077] Step 202, obtaining the characteristic value of the instant heating device;

[0078] Step 204, determining the second correspondence between the driving value and the water flow velocity of the water pump according to the first correspondence between the characteristic value and the water flow velocity in the water pump;

[0079] Step 206, determining the water output of the water pump at any moment according to the second correspondence;

[0080] Step 208, comparing the water output with the preset water output volume to determine whether to stop the water output.

[0081] In this embodiment, based on the correspondence between the driving value of the water pump and the water flow rate, i.e., the second correspondence, the water flow rate at each moment during the water outlet process of the water pump can be accurately obtained, thereby improving the quantitative water outlet accuracy. According to the water flow rate, the volume of water that has flowed out of the water pump at the current moment, i.e., the water output, can be calculated. By comparing the water output with the preset water output volume, it can be determined whether to stop the water outlet, and the quantitative water outlet requirement can be achieved. Through the technical solution of the present invention, the quantitative water outlet accuracy can be effectively improved, and the quantitative water outlet effect can be enhanced.

[0082] Among them, the preset water output volume is the target water output volume set by the user.

[0083] In the above technical solution, in step 206, the step of determining whether to stop the water outlet specifically includes: stopping the water outlet based on the water output being equal to the preset water output volume.

[0084] In this embodiment, by determining whether the water output of the water pump has reached the preset water output volume, and stopping the water outlet when the water output reaches the preset water output volume, the quantitative water outlet is completed.

[0085] In an embodiment of the present invention, a control method for an instant heating device is proposed, as Figure 3 shown. This control method includes:

[0086] Step 302, obtaining the characteristic value of the instant heating device;

[0087] Step 304, determining the second correspondence between the driving value of the water pump and the water flow rate according to the first correspondence between the characteristic value and the water flow rate in the water pump;

[0088] Step 306, based on the start of water outlet of the water pump, obtaining the first driving value of the water pump and recording the water outlet time;

[0089] Step 308, determining the first water flow rate corresponding to the first driving value according to the second correspondence; determining the water output according to the first water flow rate and the water outlet time;

[0090] Step 310, comparing the water output with the preset water output volume to determine whether to stop the water outlet; stopping the water outlet based on the water output being equal to the preset water output volume.

[0091] In this embodiment, when the water pump starts to discharge water, the first driving value of the water pump, that is, the current driving value, is obtained, and the water outlet time is recorded at the same time. Based on the correspondence between the driving value of the water pump and the water flow rate, that is, the second correspondence, the water flow rate corresponding to the current driving value can be calculated in real time. Combining the water outlet time, the total volume of water that has flowed out, that is, the water output of the water pump, can be counted. Through the technical solution of the present invention, the water output can be accurately calculated, and the quantitative water outlet effect can be ensured.

[0092] It should be noted here that the first driving value is the driving value of the main board feed pump and is therefore known. Additionally, it should also be noted that the first driving value is the current driving value of the pump. To ensure the water output effect, the first driving value is variable, and therefore, the corresponding water flow rate also changes.

[0093] In a specific implementation of the present invention, the step of determining the water output volume based on the first water flow rate and the water output time specifically includes calculating according to the following formula:

[0094]

[0095] Wherein, V is the total volume of water that has flowed out (water output volume), the 0 moment is the moment when the user just starts to let out water, the k moment is the current moment, t is the acquisition time interval, and v n is the instantaneous water flow rate (first water flow rate) collected every t time interval during the water output process.

[0096] In an embodiment of the present invention, a control method for an instant heating device is proposed. As Figure 4 shown, the control method includes:

[0097] Step 402, obtaining the characteristic value of the instant heating device;

[0098] Step 404, determining different second water flow rates of the water pump under different second driving values according to the characteristic value and the first correspondence;

[0099] Step 406, determining the second correspondence between the driving value and the water flow rate of the water pump according to the different second water flow rates and different second driving values;

[0100] Step 408, based on the start of water output by the water pump, obtaining the first driving value of the water pump and recording the water output time;

[0101] Step 410, determining the first water flow rate corresponding to the first driving value according to the second correspondence; determining the water output volume according to the first water flow rate and the water output time;

[0102] Step 412, comparing the water output volume with the preset water output volume; based on the water output volume being equal to the preset water output volume, stopping the water output.

[0103] In this embodiment, according to the characteristic value and the first corresponding relationship, different second water flow rates of the water pump under different second driving values can be obtained. The second driving value is a given fixed driving value, so that multiple sets of data of the fixed driving value and the corresponding water flow rate are obtained. Then, based on these data, the second corresponding relationship between the driving value and the water flow rate of the water pump is determined. Through the technical solution of the present invention, the second corresponding relationship between the driving value and the water flow rate of the water pump can be calculated through the machine characteristic value and the first corresponding relationship. By using the second corresponding relationship, the water flow rate at each moment during the water outlet process can be accurately calculated, so as to obtain a more accurate quantitative water outlet accuracy.

[0104] In a specific implementation of the present invention, through experiments, a general formula for the characteristic value and the water flow rate of the water pump under different fixed driving values can be obtained:

[0105] (1) When the driving value is P1, v P1 = g 1 (M); ①

[0106] Where, v P1 is the actual water flow rate of the water pump when the second driving value is P1, with the unit of ml / minute;

[0107] (2) When the driving value is P2, v P2 = g 2 (M); ②

[0108] Where, v P2 is the actual water flow rate of the water pump when the second driving value is P2, with the unit of ml / minute;

[0109] …

[0110] (3) When the driving value is Pn, v Pn = g n (M); ③

[0111] Where, v Pn is the actual water flow rate of the water pump when the second driving value is Pn, with the unit of ml / minute.

[0112] In the above formulas, M is the characteristic value of the machine, that is, the heating capacity value. This value can be obtained in the form of fixing the power of the heating component and the driving value of the fixed water pump when the instant heating device passes the line in the factory or when it is used by the user.

[0113] Substitute the characteristic value M of the machine into the above formulas ①, ②, ③, etc. respectively, and calculate the instantaneous water flow rates v P1 , v P2 … v Pn .

[0114] In an embodiment of the present invention, a control method for an instant heating device is proposed. As Figure 5 shown, the control method includes:

[0115] Step 502, in response to a quantitative water output instruction, obtain the characteristic value of the instant heating device, and determine a preset water output volume according to the quantitative water output instruction;

[0116] Step 504, determine different second water flow rates of the water pump at different second driving values according to the characteristic value and the first correspondence;

[0121] In this embodiment, when receiving a quantitative water output instruction, respond to the quantitative water output instruction, obtain the characteristic value of the instant heating device, and determine a preset water output volume according to the quantitative water output instruction, where the preset water output volume is the target water output volume set by the user.

[0122] Furthermore, based on the first correspondence between the characteristic value and the water flow rate in the water pump, determine the second correspondence between the driving value and the water flow rate of the water pump. After obtaining the second correspondence, the water flow rate at each moment during the water output process can be accurately calculated through the second correspondence, so as to obtain a more accurate quantitative water output accuracy.

[0123] Furthermore, based on the water flow rate at each moment and combined with the water output time, the water output volume at each moment during the water output process can be calculated. By comparing the water output volume with the preset water output volume to determine whether to stop water output, the quantitative water output requirement can be achieved.

[0124] Specifically, when the water output volume is equal to the preset water output volume, stop water output, and the quantitative water output is completed.

[0125] Specifically, the preset water output volume can be set according to actual needs when the instant heating device leaves the factory, such as 80 ml, 100 ml, 120 ml, 200 ml, 400 ml, etc. When used at the user end, the corresponding water output volume can be selected, or the target water output volume can be set.

[0126] In any of the above embodiments, before the step of obtaining the characteristic value of the instant heating device, it further includes: storing the characteristic value of the instant heating device.

[0127] In this embodiment, when the instant heating device passes through the factory line or is used at the user end, the characteristic value of the device can be obtained by fixing the power of the heating component and the driving value of the water pump. By storing the characteristic value of the instant heating device, the characteristic value will be written into the EEPROM of the control main board and will not be lost when the power is off, thereby ensuring the stability of the quantitative water output of the device. Of course, it can also be stored in other memories, such as ROM, RAM, etc.

[0128] In addition, when the user has a need for quantitative water output, the software can directly obtain the characteristic value of the device without having to execute the relevant program for obtaining the characteristic value of the device again, which helps to quickly respond to the user's water output demand and ensure the water output effect.

[0129] In any of the above embodiments, the first correspondence has various forms, such as curve form, function form, and relation table form. Specifically, the first correspondence includes: a first relation curve, and / or a first relation function, and / or a first relation table.

[0130] In any of the above embodiments, the second correspondence has various forms, such as curve form, function form, and relation table form. Specifically, the second correspondence includes: a second relation curve, and / or a second relation function, and / or a second relation table.

[0131] In this embodiment, on the one hand, the water flow rate corresponding to the fixed driving value corresponding to the characteristic value can be obtained through various methods, such as the curve corresponding method, the function calculation method, and the table lookup method. On the other hand, the water flow rate corresponding to the current driving value of the water pump can be obtained through various methods, such as the curve corresponding method, the function calculation method, and the table lookup method. This can adapt to various working scenarios, facilitate better control of the water output temperature and volume, and improve the water output effect.

[0132] In any of the above embodiments, the first relation function is determined according to the first relation curve; the second relation function is determined according to the second relation curve.

[0133] In this embodiment, the first relation function between the characteristic value and the water flow rate in the water pump can be obtained through the first relation curve. Similarly, the second relation function between the driving value - water flow rate of the water pump can be obtained according to the second relation curve.

[0134] In some embodiments of the present invention, through experiments, it is obtained that the characteristic value of the instant heating device and the water flow rate of the water pump driven at a fixed driving value are in a linear relationship.

[0135] In a specific embodiment of the present invention, when the fixed driving value of the water pump is obtained, the general formula for the characteristic value M and the water flow velocity is:

[0136] v = kM + b;

[0137] (1) When the driving value is P1, v P1 = k 1 M + b 1 ;

[0138] wherein, v P1 is the actual water flow velocity of the water pump when the second driving value is P1, with the unit of ml / min; k 1 , b 1 are constants and can be obtained through experiments.

[0139] (2) When the driving value is P2, v P2 = k 2 M + b 2 ;

[0140] wherein, v P2 is the actual water flow velocity of the water pump when the second driving value is P2, with the unit of ml / min; k 2 , b 2 are constants and can be obtained through experiments.

[0141] …

[0142] (3) When the driving value is Pn, v Pn = k n M + b n ;

[0143] wherein, v Pn is the actual water flow velocity of the water pump when the second driving value is Pn, with the unit of ml / min; k n , b n are constants and can be obtained through experiments.

[0144] Substituting the M value of the present machine into the above formula, multiple sets of corresponding data of the second driving value and the second water flow velocity can be obtained, so as to determine the characteristic curve of the driving value - water flow velocity of the water pump. Further, the characteristic function can be obtained based on the characteristic curve. Further, the relationship table of the driving value - water flow velocity can be obtained based on the characteristic curve or the characteristic function.

[0145] When there is a quantitative water outlet requirement at the user end, the water flow velocity at each moment during the water outlet process can be calculated through the above-obtained characteristic curve or characteristic function or relationship table, so as to obtain a more accurate quantitative water outlet accuracy.

[0146] In another specific embodiment of the present invention, the driving value - water flow velocity characteristic curve is obtained through experiments and is very close to a quadratic function.

[0147] Those skilled in the art should understand that in any of the above embodiments, the first correspondence and the second correspondence are not limited to a linear relationship or a quadratic function relationship.

[0148] In another specific embodiment of the present invention, by performing flow rate tests on a large number of water pumps and based on the working principle of a DC water pump, a drive value - water flow velocity characteristic curve is obtained, which is very close to a linear function and has the format of:

[0149] v = kP + b;

[0150] Where P is the pulse width (PWM) drive value of the main board for the water pump; v is the instantaneous water flow velocity in the water pump (unit: ml / minute); k and b are constants obtained through experiments.

[0151] It should be noted that P can be either voltage or current.

[0152] Next, a control method for the instant heating device of the present invention will be described in detail through an embodiment.

[0153] 1. By performing flow rate tests on a large number of water pumps and based on the working principle of a DC water pump, we obtain a second correspondence between the drive value and the water flow velocity, which is very close to a linear function and has the format of:

[0154] v = kP + b; ⑥

[0155] Where P is the pulse width (PWM) drive value of the main board for the water pump; v is the instantaneous water flow velocity in the water pump (unit: ml / minute); k and b are constants obtained through experiments.

[0156] 2. When the instant heating device passes through the production line in the factory, the calibration equipment writes the power of the heating component carried by each machine into the control main board.

[0157] 3. When the instant heating device passes through the production line in the factory or is used at the user end, the instant heating device software obtains the characteristic value M of this machine in the form of fixing the power of the instant heating pipe and fixing the drive voltage of the water pump. The physical meaning of this characteristic value is a symbol of the maximum water temperature rise value that different machines can achieve under the same power and the same water pump drive voltage. The larger M is, the greater its maximum temperature rise is, that is, the stronger the heating ability of the machine. The M value will be written into the EEPROM of the control main board and will not be lost when the power is off.

[0158] 4. Through experiments, the general formula for the characteristic value M and the water flow velocity when the water pump is at a fixed drive value is:

[0159] (1) When the drive value is 1200, v 1200 = k 1 M + b1 ; ④

[0160] Among them, v 1200 is the actual water flow velocity of the water pump when the second driving value is 1,200, with the unit of ml / min; k 1 , b 1 are constants and can be obtained through experiments.

[0161] (2) When the driving value is 2,800, v 2800 = k 2 M + b 2 ; ⑤

[0162] Among them, v 2800 is the actual water flow velocity of the water pump when the second driving value is 2,800, with the unit of ml / min; k 2 , b 2 are constants and can be obtained through experiments.

[0163] Based on the above preparations, data, and formulas, when the control software receives a command for quantitative water discharge, it will perform flow calculation processing according to the following algorithm:

[0164] 1. Obtain the characteristic value M of the local machine, substitute the M value of the local machine into formulas ④ and ⑤ respectively, and calculate the instantaneous water flow velocities v 1200 and v 2800 of the local machine when the driving values are 1,200 and 2,800 respectively;

[0165] 2. Substitute the driving values 1,200, 2,800 and the corresponding v 1200 and v 2800 into formula ⑥ respectively to form a system of equations:

[0166]

[0167] By solving this system of equations, obtain k m , b m .

[0168] Substitute k m , b m into formula ⑥ to obtain the water pump characteristic function of the local machine:

[0169] v = k m P + b m

[0170] Thus, the characteristic function of the driving value - water flow velocity of the water pump is obtained.

[0171] 3. Since P is the driving value given by the main board to the water pump and is known, during the water discharge process, the current water flow velocity can be calculated through the second corresponding relationship moment, and the total volume of the discharged water can be counted.

[0172] Specifically, the calculation is performed according to the following formula:

[0173]

[0174] Wherein, V is the total volume of the water that has flowed out (water output), the 0 moment is the moment when the user starts to discharge water, the k moment is the current moment, t is the acquisition time interval, and v n is the instantaneous water flow velocity (the first water flow velocity) collected every t time interval during the water discharge process.

[0175] 4. Compare the total volume of the water that has flowed out (water output) with the target water output volume (preset water output volume) set by the user in real time. When the total volume of the water that has flowed out has reached the target water output volume set by the user, stop discharging water, and the quantitative water discharge is completed.

[0176] It should be noted here that the corresponding relationship between the driving value of the water pump - water flow velocity, that is, the second corresponding relationship, is not limited to a linear relationship; the corresponding relationship between the characteristic value of the instant heating device - water flow velocity, that is, the first corresponding relationship, is also not limited to a linear relationship.

[0177] In addition, the PWM values 1200 and 2800 are only two specific embodiments of the second driving value in the present invention, but are not limited thereto. The second driving value can also be set to any value within its value range. In this embodiment, the second driving value can also be, for example, 500, 800, 1000, 2500, etc.

[0178] Those skilled in the art should understand that the given fixed driving value is not limited to 1200 and 2800, and can be arbitrarily selected within the value range of the driving value of the water pump.

[0179] An embodiment of the second aspect of the present invention provides a control device 600 for an instant heating device. The instant heating device includes a water pump. The control device 600 for the instant heating device will be described through the following embodiments.

[0180] In an embodiment of the present invention, as Figure 6 shown, the control device 600 for the instant heating device includes:

[0181] An acquisition unit 602, configured to acquire the characteristic value of the instant heating device;

[0182] A calculation unit 604, configured to determine the second corresponding relationship between the driving value of the water pump and the water flow velocity according to the first corresponding relationship between the characteristic value and the water flow velocity in the water pump;

[0183] The calculation unit 604 is further configured to determine the water output of the water pump at any moment according to the second corresponding relationship.

[0184] The control device 600 of the instant heating device provided by the embodiment of the present invention, wherein the instant heating device includes a water pump. The characteristic value of the instant heating device is obtained by the obtaining unit 602, and according to the first corresponding relationship between the characteristic value and the water flow rate in the water pump, the calculation unit 604 can determine the second corresponding relationship between the driving value of the water pump and the water flow rate. After obtaining the second corresponding relationship, the calculation unit 604 can obtain the instantaneous flow rate of the water pump at the current moment through the second corresponding relationship, so as to determine the water output at any moment during the water outlet process of the water pump. This avoids using the default corresponding relationship between the driving value of the water pump and the water flow rate in the related art to calculate the water output, thereby effectively improving the quantitative water output accuracy.

[0185] It should be noted here that the instant heating device further includes a heating component, and the characteristic value refers to the heating capacity value reflected by the maximum stable temperature rise that different instant heating devices can achieve under the same power of the heating component and the same driving value of the water pump. Those skilled in the art can understand the concept of the above heating capacity value.

[0186] Therefore, through the corresponding relationship between the characteristic value and the water flow rate in the water pump, the actual water flow rate of the water pump under a fixed driving value can be determined, so that the corresponding relationship between the driving value of the water pump and the water flow rate can be accurately determined, and then the water flow rate at each moment during the water outlet process can be accurately calculated, obtaining a more accurate quantitative water output accuracy.

[0187] Among them, the driving value of the water pump can be either voltage or current. The instant heating device can be an instant heating module with an instant heating function, or a device carrying the instant heating module, such as a water dispenser, a water heater, etc.

[0188] Through the control device 600 of the instant heating device provided by the embodiment of the present invention, the characteristic values of different machines can be obtained. According to the first corresponding relationship between the characteristic value and the water flow rate in the water pump, the second corresponding relationship between the driving value of the water pump and the water flow rate of different machines can be obtained. After obtaining the second corresponding relationship, the water flow rate at each moment during the water outlet process can be accurately calculated through the second corresponding relationship, so as to obtain a more accurate quantitative water output accuracy.

[0189] In an embodiment of the present invention, the control device 600 of the instant heating device further includes a control unit, and the control unit is used to compare the water output with a preset water output volume to determine whether to stop the water outlet.

[0190] Among them, the preset water output volume is the target water output set by the user.

[0191] Further, the step of the control unit determining whether to stop the water outlet specifically includes: stopping the water outlet based on the water output being equal to the preset water output volume.

[0192] In this embodiment, the control unit compares the water output of the water pump with the preset water output volume. When the water output is equal to the preset water output volume, the control unit controls the instant heating device to stop discharging water, thereby completing the quantitative water discharge.

[0193] In an embodiment of the present invention, the step of the calculation unit 604 determining the water output of the water pump at any moment according to the second corresponding relationship specifically includes: based on the start of water discharge of the water pump, obtaining the first driving value of the water pump and recording the water discharge time; determining the first water flow rate corresponding to the first driving value according to the second corresponding relationship; and determining the water output according to the first water flow rate and the water discharge time.

[0194] In this embodiment, when the water pump starts to discharge water, the acquisition unit 602 acquires the first driving value of the water pump, that is, the current driving value, and at the same time records the water discharge time. The calculation unit 604 can calculate the water flow rate corresponding to the current driving value in real time through the second corresponding relationship between the driving value and the water flow rate of the water pump, and combined with the water discharge time, can count the total volume of the discharged water, that is, the water output of the water pump. Through the embodiments of the present invention, the quantitative water discharge accuracy can be further improved, and the quantitative water discharge effect can be improved.

[0195] It should be noted here that the first driving value is the driving value given by the main board to the water pump, so it is known. In addition, it should also be noted that the first driving value is the current driving value of the water pump. To ensure the water discharge effect, the first driving value is variable. Therefore, the corresponding water flow rate is also variable.

[0196] In an embodiment of the present invention, the step of the calculation unit 604 determining the second corresponding relationship between the driving value and the water flow rate of the water pump according to the first corresponding relationship between the characteristic value and the water flow rate in the water pump specifically includes: determining different second water flow rates of the water pump under different second driving values according to the characteristic value and the first corresponding relationship; and determining the second corresponding relationship between the driving value and the water flow rate of the water pump according to the different second water flow rates and different second driving values.

[0197] In this embodiment, the calculation unit 604 can obtain different second water flow rates of the water pump driven by different second driving values according to the characteristic value and the first corresponding relationship. The second driving value is the given fixed driving value, so as to obtain multiple sets of data of the fixed driving value and the water flow rate, and then determine the second corresponding relationship between the driving value and the water flow rate of the water pump according to these data.

[0198] Through the embodiments of the present invention, the second corresponding relationship between the driving value and the water flow rate of the water pump can be calculated through the machine characteristic value and the first corresponding relationship. Through the second corresponding relationship, the water flow rate at each moment during the water discharge process can be accurately calculated, so as to obtain a more accurate quantitative water discharge accuracy.

[0199] In one embodiment of the present invention, the step in which the acquisition unit 602 acquires the characteristic value of the instant heating device specifically includes: in response to a quantitative water outlet instruction, acquiring the characteristic value of the instant heating device.

[0200] In this embodiment, when receiving the quantitative water outlet instruction, the acquisition unit 602 responds to the quantitative water outlet instruction and acquires the characteristic value of the instant heating device. Further, based on the first correspondence between the characteristic value and the water flow velocity in the water pump, the calculation unit 604 determines the second correspondence between the driving value of the water pump and the water flow velocity. After obtaining the second correspondence, the control unit can accurately calculate the water flow velocity at each moment during the water outlet process through the second correspondence, thereby obtaining a more accurate quantitative water outlet accuracy.

[0201] Further, the acquisition unit 602 determines a preset water outlet volume according to the quantitative water outlet instruction.

[0202] In this embodiment, when receiving the quantitative water outlet instruction, the acquisition unit 602 can determine the preset water outlet volume according to the quantitative water outlet instruction. Wherein, the preset water outlet volume is the target water output set by the user.

[0203] In one embodiment of the present invention, before the step in which the acquisition unit 602 acquires the characteristic value of the instant heating device, the control unit is further configured to store the characteristic value of the instant heating device.

[0204] In this embodiment, when the instant heating device passes through the factory line or is used at the user end, the control unit can learn the characteristic value of this machine by fixing the power of the fixed heating component and the driving value of the fixed water pump. By storing the characteristic value of the instant heating device, the characteristic value will be written into the EEPROM of the control main board and will not be lost when the power is off, thereby ensuring the stability of the quantitative water outlet of this machine.

[0205] In addition, when the user has a need for quantitative water outlet, the acquisition unit 602 can directly acquire the characteristic value of this machine without the control unit executing the relevant program for learning the characteristic value of this machine again, which helps to quickly respond to the user's water outlet demand.

On the other hand, the water flow velocity corresponding to the current driving value of the water pump can be obtained through various methods such as the curve corresponding method, the function calculation method, and the look-up table method. This can adapt to various working scenarios, facilitate better control of the outlet water temperature and the outlet water volume, and improve the outlet water effect.

[0209] In any of the above embodiments, the calculation unit 604 is further configured to determine a first relationship function according to the first relationship curve; and determine a second relationship function according to the second relationship curve.

[0210] In this embodiment, the calculation unit 604 can obtain the first relationship function between the two through the first relationship curve of the characteristic value - water flow velocity in the water pump. Similarly, the calculation unit 604 can obtain the second relationship function between the two according to the second relationship curve of the driving value - water flow velocity of the water pump.
