Detailed Description
Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.
The instant heating water dispenser, the water outlet curve correction method and device thereof and the storage medium according to the embodiment of the invention are described below with reference to the accompanying drawings.
FIG. 1 is a flowchart of a method for correcting a water outlet curve of an instant heating water dispenser according to one embodiment of the present invention.
As shown in fig. 1, the present invention provides a method for correcting a water outlet curve of an instant heating water dispenser, which comprises the following steps:
s10, acquiring current driving parameters of a water pump in the instant heating water dispenser and acquiring current working parameters of the instant heating water dispenser.
Specifically, since the instant heating water dispenser heats up the speed faster, so if the water outlet is slower or the water outlet is faster, the heating temperature will be affected, for example, when the heating temperature of the drinking water needs to be hotter to 90 ℃, the water outlet speed corresponding to the temperature will be generated in the water dispenser, and then the water outlet speed can be controlled by the driving voltage of the water pump in the water dispenser, and the water outlet amount of the water pump cannot be output according to the preset water outlet amount due to the errors of the manufacturing process or the conditions of different use environments, and then the difference between the water outlet temperature and the target temperature will be caused.
Since the water output of the water pump is determined according to the driving voltage of the water pump regardless of the errors caused by the process errors or the different use environments, the embodiment needs to acquire the real-time driving voltage of the water pump in the instant heating water dispenser when correcting the water output curve, namely, acquire the current driving parameter of the water pump, and of course, the current driving parameter can be represented not only by the driving voltage of the water pump but also by the data related to the driving voltage of the water pump, such as PWM (Pulse Width Modulation ) value and the like.
According to the embodiment, when a user operates the instant heating water dispenser to discharge hot water, the current driving parameters of the water pump in the instant heating water dispenser can be obtained, and particularly, the water pump curve correction module can be arranged in the instant heating water dispenser, and when the user operates the water dispenser to discharge hot water, the water pump curve correction module is activated, so that the corresponding script program can be operated to obtain the current driving parameters of the water pump, and the current working parameters of the instant heating water dispenser can be obtained. It will be appreciated that in different embodiments, the current operating parameters of the instant water dispenser that need to be obtained are different, wherein the current operating parameters of the instant water dispenser include, but are not limited to, parameters such as real-time power of the instant water dispenser, a difference between the outlet water temperature and the inlet water temperature, a supply voltage, a rated voltage, and a rated power.
S20, determining the current flow rate of the water pump according to the current working parameters, and determining the current curve coordinate of the water pump according to the current driving parameters and the current flow rate of the water pump.
Specifically, after the current working parameter of the instant water dispenser is obtained, the current flow rate of the water pump can be determined according to the current working parameter, and it can be understood that the specific determination mode of the current flow rate of the water pump can be determined in different modes according to different working parameters.
After determining the current flow rate of the water pump, the current flow rate of the water pump and the current driving parameter of the water pump can be used as a new coordinate, and the coordinate represents the corresponding current flow rate of the instant heating water dispenser under the driving of the current driving parameter. It can be understood that the instant water dispenser is provided with a default water outlet curve, namely a driving parameter-water outlet flow rate curve, when leaving the factory, and the new coordinates determined by the application are the corresponding relation between the driving parameter and the water outlet flow rate, which are determined by the instant water dispenser according to the current real-time environment.
S30, correcting the function coefficient corresponding to at least part of the line segments of the water outlet curve stored in the instant heating water dispenser according to the current curve coordinates so as to correct the water outlet curve stored in the instant heating water dispenser.
Specifically, after determining the current curve coordinate of the water pump according to the current driving parameter and the current flow rate of the water pump, the current curve coordinate is utilized to correct the water outlet curve stored in the instant heating water dispenser, and at least part of the line segment of the water outlet curve can be corrected. For example, as shown in table 1, the water output curve in the present embodiment is a linear function, i.e., y=kx+b, where y is the flow rate in the present embodiment, x is the PWM value, and k and b are preset parameters respectively. The water outlet curve is divided into a plurality of sections, wherein each section of the line section is provided with different preset parameters k and b for determining the shape of the linear function, and the line section is corrected by adjusting the preset parameters so that the corresponding relation between the driving parameters and the flow rate can accord with the current use environment of the instant heating water dispenser.

In one embodiment of the invention, the current operating parameters include average power and average temperature rise of the instant hot beverage machine over a preset time.
Specifically, in this embodiment, in the process of obtaining the current working parameter of the instant heating water dispenser, the time that the temperature of the water dispenser changes greatly in the heating process can be omitted first until the water outlet temperature is stable, and then the average power and the average temperature rise in the preset time are obtained, so that the relatively stable temperature can be obtained, and inaccurate obtaining of the current working parameter caused by too large temperature fluctuation can be prevented. As shown in fig. 2, the water outlet temperature is stable at about 11:17:20, so that the average power and average temperature rise in a preset time can be obtained from the time, the preset time can be specifically 6 seconds, and of course, other times can be also used, and the water outlet temperature is not specifically limited herein, and can be selected by a user according to actual use conditions.
In this embodiment, the current flow rate of the water pump is calculated according to the following formula:wherein v is Currently, the method is that For the current flow rate, pn is the average power, c is the specific heat capacity of water, ρ is the density of water, and DeltaT is the average temperature rise.
Specifically, after the average power and average temperature rise in the preset time are obtained, the formula can be followed Determining the current flow rate, wherein the formula +.>Specifically, the conversion can be performed according to the formula pt=cm Δt.
Therefore, in this embodiment, the current flow rate is calculated according to the average power and the average temperature rise, and then the current curve coordinate of the water pump can be determined according to the current flow rate and the current driving parameter, and then the current curve coordinate is used to correct the water outlet curve.
In another embodiment of the present invention, the current operating parameters include an average power supply voltage and an average temperature rise of the instant water dispenser within a preset time, and a rated voltage and a rated power of the instant water dispenser, wherein determining the current flow rate of the water pump according to the current operating parameters includes: determining equivalent temperature rise according to the average power supply voltage, the average temperature rise and the rated voltage; and determining the current flow rate of the water pump according to the equivalent temperature rise and the rated power.
Specifically, in this embodiment, the current operating parameters include an average power supply voltage and an average temperature rise of the instant water dispenser within a preset time, and a rated voltage and a rated power of the instant water dispenser, and it is understood that the preset time is the same as the preset time in the above embodiment, and after the temperature is determined to be stable, the average power supply voltage and the average temperature rise within a preset time, for example, 6 seconds, are averaged to obtain the average power supply voltage and the average temperature rise.
After the average power supply voltage, the average temperature rise, the rated voltage and the rated power are obtained, the equivalent temperature rise can be determined according to the average power supply voltage, the average temperature rise and the rated voltage, and a specific calculation formula is as followsWherein DeltaT Equivalent means Is equivalent to temperature rise, U is average power supply voltage, U Forehead (forehead) For rated voltage, Δt is the average temperature rise.
It can be appreciated that the equivalent temperature rise refers to the current average temperature rise corresponding to the temperature rise under the condition that the instant heating water dispenser is at rated voltage and rated power, and in particular, the equivalent temperature rise can be calculated according to the formulaCalculated->
It should be noted that, in this embodiment, the preset time includes a first time period and a second time period that overlap in time, where U is an average power supply voltage of the instant heating water dispenser in the first time period, and Δt is an average temperature rise of the instant heating water dispenser in the second time period.
Specifically, for example, the preset time is 6 seconds, then during the 6 seconds, the real-time power supply voltage and the real-time temperature rise can be continuously recorded, and if the driving parameters in the water output curve are represented by PWM values, the real-time PWM values can also be recorded. After the real-time power supply voltage and the real-time temperature rise are continuously recorded, the average power supply voltage of the instant heating water dispenser can be calculated by using the first time period, wherein the first time period in the embodiment is 0-4 seconds, namely the first 4 seconds of the 6 seconds preset time. In this embodiment, the average temperature rise of the instant water dispenser is an average temperature rise in a second period of time, and the second period of time may be 2-6 seconds, that is, the last 4 seconds of the preset time of 6 seconds. It should be noted that, in this embodiment, the preset time is divided into two time periods with overlapping time, where since the supply voltage change is small, the average supply voltage is acquired only by recording the supply voltage in the first time period, and the recording times and recording times of the real-time voltage can be reduced by using the first time period, so as to further improve the acquisition speed. And since the longer the heating time, the more stable the temperature, then when recording the average temperature rise, the temperature rise in the second time period can be recorded, and then the average temperature rise in the second time period can be calculated to obtain a more stable and accurate average temperature rise.
In this embodiment, the current flow rate of the water pump is calculated according to the following formula:wherein DeltaT Equivalent means Is equivalent to temperature rise, v Currently, the method is that At the current flow rate, P Forehead (forehead) For rated power, c is the specific heat capacity of water and ρ is the density of water.
Specifically, after the average power supply voltage and the rated power of the instant heating water dispenser within the preset time are obtained and the equivalent temperature rise within the preset time is calculated, the formula can be followedDetermining the current flow rate, wherein the formula +.>Specifically, the conversion can be performed according to the formula pt=cm Δt.
Therefore, in this embodiment, the current flow rate is calculated according to the average power supply voltage, the rated power and the equivalent temperature rise, so that the current curve coordinate of the water pump can be determined according to the current flow rate and the current driving parameter, and then the current curve coordinate is used for correcting the water outlet curve.
In one embodiment of the present invention, as shown in fig. 3, the correction of the function coefficient corresponding to at least a part of the line segment of the water outlet curve stored in the instant hot water dispenser according to the current curve coordinate includes the following steps:
s301, determining reference point coordinates corresponding to at least one line segment in at least part of line segments according to the current curve coordinates.
Specifically, for example, the water output curve in the embodiment of the present invention is a linear function, such as y=kx+b, where x may represent a driving parameter of the instant water dispenser, and y may represent a water output of the instant water dispenser. In this embodiment, the water outlet curve is divided into a plurality of line segments, as shown in fig. 4, and the water outlet curve may be divided into 10 line segments, where it should be noted that each line segment corresponds to a reference point coordinate, where the reference point coordinate may be used to represent the line segment corresponding to the reference point coordinate. Alternatively, the reference point of each line segment may be the center point of the line segment, or may be the edge point of the line segment, which is not specifically limited herein.
After the current curve coordinate is determined, the current outlet curve line segment of the instant water dispenser can be determined according to the driving parameters in the current curve coordinate, the part line segment needing to be updated can be determined according to the line segment where the current curve coordinate is located, and then the reference point corresponding to at least one line segment is obtained from the part line segment needing to be updated.
S302, determining the function coefficient to be updated according to the current curve coordinate and the reference point coordinate.
Specifically, in some embodiments, after determining the current curve coordinate and the reference point coordinate, the function coefficients of three types of line segments, that is, the line segment corresponding to the current curve coordinate, the line segment corresponding to the reference point coordinate, and the line segment corresponding to the other reference point between the current curve coordinate and the reference point coordinate, may be updated. Of course, in other embodiments, the function coefficients of two or one of the three types of line segments corresponding to the current curve coordinate, the line segment corresponding to the reference point coordinate, and the line segment corresponding to the other reference point between the current curve coordinate and the reference point coordinate may be updated.
The specific updating mode is to determine the function coefficient to be updated according to the current curve coordinate and the reference point coordinate, for example, parameters k and b in the linear function, wherein the function coefficient corresponding to the line segment determined to be updated is updated, and the function coefficient of the line segment to be updated can be replaced by the function coefficient to be updated.
S303, updating the function coefficients corresponding to at least part of the line segments according to the function coefficients to be updated.
Specifically, after the function coefficient to be updated is obtained by calculation, the function coefficient corresponding to the line segment to be updated may be updated by using the function coefficient to be updated, and specifically, the function coefficient corresponding to the line segment to be updated may be replaced by using the function coefficient to be updated. Of course, other updating methods may be adopted, for example, the function coefficients to be updated and the function coefficients corresponding to at least part of the line segments are averaged, the obtained average function coefficients are updated to the function coefficients corresponding to at least part of the line segments, and the average function coefficients are specifically replaced for the function coefficients corresponding to at least part of the line segments.
In this embodiment, determining the function coefficient to be updated according to the current curve coordinate and the reference point coordinate includes the following steps:

Specifically, in one embodiment, as shown in fig. 4, assuming that the abscissa of the current curve coordinate is between 14 volts and 15 volts, the abscissa is greater than the abscissa of the current curve coordinate as the high point reference point coordinate, and the abscissa is smaller than the abscissa of the current curve coordinate as the low point reference point coordinate among the reference point coordinates of all the line segments. Of course, other determination methods may be used to determine the high point reference point and the low point reference point, wherein, for example, by comparing the values of the ordinate, when the ordinate of the reference point coordinate is greater than the ordinate of the current curve coordinate, it may be determined as the high point reference point coordinate, and if it is less than the low point reference point coordinate. Of course, the determination may be performed by other determination methods, and is not particularly limited herein.
After the high point reference point coordinates and the low point reference point coordinates are determined, a line segment to be updated can be determined according to the two reference point coordinates and the current curve coordinates, wherein the mode of forming different line segments to be updated according to different reference points can be different or the same. Here, the water outlet curve line segment formed by the line segment corresponding to the current curve coordinate and the high point reference point coordinate and the line segment between the current curve coordinate and the high point reference point coordinate may be corrected to be the first line segment. For the low point reference point coordinates, the line segment corresponding to the low point reference point coordinates and the water outlet curve line segment formed by the line segment between the current curve coordinates and the low point reference point coordinates can be corrected to be the second straight line segment.
In this specific example, after the first straight line segment and the second straight line segment are determined, the first function coefficient corresponding to the first straight line segment may be substituted for the function coefficient corresponding to the line segment corresponding to the current curve coordinate and the high point reference point coordinate and the line segment between the current curve coordinate and the high point reference point coordinate, and the second function coefficient corresponding to the second straight line segment may be substituted for the function coefficient corresponding to the line segment corresponding to the low point reference point coordinate and the line segment between the current curve coordinate and the low point reference point coordinate.

Similarly, the line segments between the current curve coordinate and the low point reference point coordinate are the line segments 6 and 7, and the function coefficients corresponding to the line segments 6 and 7 may be updated according to the second function coefficient, where the second function coefficient may be solved according to the current curve coordinate and the low point reference point coordinate, and the solving manner is the same as that of the first function coefficient, which may be specifically referred to the description of the above embodiment and will not be repeated herein.

s601, forming the current curve coordinate and the high point reference point coordinate into a first straight line segment, and calculating a function coefficient corresponding to the first straight line segment.
Specifically, after determining the current curve coordinate and the high point reference point coordinate, the current curve coordinate and the high point reference point coordinate may form a first straight line segment, where if other water outlet curve segments may or may not be included between the high point reference point coordinate and the current curve coordinate. For example, when no other water-out curve line segment is included between the current curve coordinate and the high point reference point coordinate, the first line segment may be composed of the water-out curve line segment corresponding to the current curve coordinate and the water-out curve line segment corresponding to the high point reference point coordinate. When other water outlet curve line segments are included between the current curve coordinate and the high point reference point coordinate, the first line segment not only includes the water outlet curve line segment corresponding to the current curve coordinate and the water outlet curve line segment corresponding to the high point reference point coordinate, but also includes other line segments included between the two line segments.

Because each of the corresponding water-out curve segments in the first straight line segment has a function coefficient, after the function coefficient of the first straight line segment is calculated, the function coefficient can be replaced by the function coefficient of each of the corresponding water-out curve segments in the first straight line segment, as shown in table 5, wherein the line segment 6 is the water-out curve segment corresponding to the current curve coordinate, the first straight line segment comprises the line segment 4, the line segment 5 and the line segment 6, the function coefficients k1 and b1 are the function coefficients of the first straight line segment, and after the function coefficients k1 and b1 are calculated, the function coefficients corresponding to the line segment 4, the line segment 5 and the line segment 6 in table 5 are replaced.

After the third straight line segment is determined, the function coefficient corresponding to the third straight line segment can be calculated according to the updated coordinates and the coordinates of the low point reference point. For example, according to the updated coordinates and the coordinates of the low point reference point, the function coefficients corresponding to the third straight line segment may be calculated to be k2 and b2, and the water outlet curve segment adapted to the coordinates of the low point reference point is segment 8, and the third straight line segment may be composed of segment 8 and segment 7, as shown in table 5, in this embodiment, the function coefficients corresponding to segment 7 and segment 8 are replaced by k2 and b2.

In this embodiment, updating the function coefficients corresponding to at least part of the line segments according to the function coefficients to be updated includes: updating the function coefficient of the water outlet curve line segment corresponding to the high point reference point coordinate, the function coefficient of the water outlet curve line segment matched with the current curve coordinate and the function coefficient of the corresponding water outlet curve line segment between the current curve coordinate and the high point reference point coordinate according to the function coefficient corresponding to the first line segment; and updating the function coefficient of the water outlet curve segment corresponding to the low point reference point coordinate and the function coefficient of the corresponding water outlet curve segment between the current curve coordinate and the low point reference point coordinate according to the function coefficient corresponding to the third straight line segment.
Specifically, in this embodiment, for different segments to be updated, function coefficients corresponding to different straight-line segments are used to update their function coefficients. After determining the function coefficients of the first straight line segment and the second straight line segment, the function coefficients of the first straight line segment may be used to replace the function coefficients in the corresponding line segment to be updated, where the line segment to be updated adapted to the first straight line segment is a water outlet curve line segment corresponding to the high point reference point coordinate, a water outlet curve line segment adapted to the current curve coordinate, and a corresponding water outlet curve line segment between the current curve coordinate and the high point reference point coordinate.
