Based on the water purifier, the invention mainly provides a control method for the water purifier.
As shown in fig. 2, fig. 2 is a flowchart of a control method of the present invention, which includes the steps of:
s100, acquiring a target water outlet temperature T0.
The target outlet water temperature is a hot water temperature selected by a user, and the user can flexibly select a required hot water temperature according to actual requirements, such as 100 ℃, 90 ℃ or 80 ℃. Of course, a default hot water temperature is set in the water purifier, and if the user does not select, the default hot water temperature is determined as the target outlet water temperature.
S200, acquiring the water temperature T1 in the first pipeline 41.

S300, acquiring a corresponding preset rotating speed according to the target outlet water temperature T0 and the water temperature T1 in the first pipeline 41.
And S400, operating the water pump 5 at a preset rotating speed.
The rotating speed of the water pump 5 is determined according to the target outlet water temperature T0 and the water temperature T1 in the first pipeline 41, so that the flowing speed of water is controlled, and the accuracy of the outlet water temperature can be improved. For example, when the temperature of the water in the first pipeline 41 is greatly different from the target outlet water temperature, the flow speed of the water may be slower, and conversely, when the temperature of the water in the first pipeline 41 is smaller than the target outlet water temperature, the flow speed of the water may be faster.
It should be noted that, in practical application, the difference between the target outlet water temperature T0 and the water temperature T1 in the first pipeline 41 may be calculated first, and then the corresponding preset rotation speed is obtained according to the difference, or the ratio between the target outlet water temperature T0 and the water temperature T1 in the first pipeline 41 may be calculated first, and then the corresponding preset rotation speed is obtained according to the ratio, and so on, and such flexible adjustment and change do not depart from the principle and scope of the present invention, and should be limited within the protection scope of the present invention.
Taking the example of obtaining the corresponding preset rotation speed according to the difference between the target outlet water temperature T0 and the water temperature T1 in the first pipeline 41, in practical applications, the rotation speed corresponding to different differences may be determined through tests, then a "difference rotation speed comparison table" is formulated according to test data, the "difference rotation speed comparison table" is stored in the controller of the water purifier, after the difference between the target outlet water temperature T0 and the water temperature T1 in the first pipeline 41 is calculated, the corresponding preset rotation speed is inquired according to the "difference rotation speed comparison table", or a calculation formula may be formulated according to the test data, the calculation formula is stored in the controller of the water purifier, after the difference between the target outlet water temperature T0 and the water temperature T1 in the first pipeline 41 is calculated, the corresponding preset rotation speed is calculated according to the calculation formula, and the like, and the flexible adjustment and change do not deviate from the principle and scope of the present invention, and all should be limited in the protection scope of the present invention.
In addition, it should be noted that, in practical applications, the rotation speed of the water pump 5 may be determined according to the target outlet water temperature T0 and the water temperature T1 in the first pipeline 41, and may also be determined according to the target outlet water temperature T0 and the water temperature T2 in the normal-temperature water tank 1.
Specifically, the control method of the present invention may further include the steps of:
s100, acquiring a target water outlet temperature T0.
S200, acquiring the water temperature T2 in the normal-temperature water tank 1.
Illustratively, as shown in fig. 1, a temperature sensor, referred to as a second temperature sensor 72, is installed in the normal-temperature water tank 1, the second temperature sensor 72 is used for detecting the temperature of the water in the normal-temperature water tank 1 (i.e., the water temperature T2), and the second temperature sensor 72 is in communication connection with the controller of the water purifier so as to transmit the detected temperature data to the controller in time.
And S300, acquiring a corresponding preset rotating speed according to the target outlet water temperature T0 and the water temperature T2 in the normal-temperature water tank 1.
And S400, operating the water pump 5 at a preset rotating speed.
It should be noted that, the specific manner of "obtaining the corresponding preset rotation speed according to the target outlet water temperature T0 and the water temperature T2 in the normal-temperature water tank 1" may refer to the specific manner of "obtaining the corresponding preset rotation speed according to the target outlet water temperature T0 and the water temperature T1 in the first pipeline 41" described above, and will not be described herein again.
Preferably, the control method of the present invention further comprises the steps of:
s500, acquiring the water temperature T3 in the second pipeline 42.
Illustratively, as shown in fig. 1, a temperature sensor, referred to as a third temperature sensor 73, is installed on the second pipeline 42, the third temperature sensor 73 is used for detecting the temperature of the water in the second pipeline 42 (i.e. the water temperature T3), and the third temperature sensor 73 is in communication connection with the controller of the water purifier so as to transmit the detected temperature data to the controller in time.
And S600, correcting the rotating speed of the water pump 5 according to the water temperature T3 in the second pipeline 42 and the target outlet water temperature T0.
By correcting the rotation speed of the water pump 5 according to the water temperature T3 in the second pipeline 42 and the target outlet water temperature T0, the accuracy of the outlet water temperature can be further improved.
It should be noted that, in practical applications, the water temperature T3 in the second pipeline 42 may be directly compared with the target outlet water temperature T0, and then the rotation speed of the water pump 5 is corrected according to the comparison result, for example, if the water temperature T3 in the second pipeline 42 is greater than the target outlet water temperature T0, the rotation speed of the water pump 5 is increased; if the water temperature T3 in the second pipeline 42 is lower than the target outlet water temperature T0, the rotating speed of the water pump 5 is reduced; alternatively, the difference between the water temperature T3 in the second pipeline 42 and the target outlet water temperature T0 may be calculated, and then the rotation speed of the water pump 5 may be corrected according to the difference, and so on, and such flexible adjustment and change do not depart from the principle and scope of the present invention, and should be limited within the protection scope of the present invention.
Preferably, the step of "correcting the rotation speed of the water pump 5 according to the water temperature T3 in the second pipeline 42 and the target outlet water temperature T0" specifically includes:
s610, calculating the difference delta 1 between the water temperature T3 in the second pipeline 42 and the target outlet water temperature T0.
Where Δ 1= T3-T0.
And S620, comparing the difference Delta 1 with the first preset value A1 and the second preset value A2 respectively.
Wherein the first preset value A1 is a negative number, the second preset value A2 is a positive number, namely A1 is less than 0, and A2 is more than 0.
And S630, if the difference delta 1 is smaller than the first preset value A1, reducing the rotating speed of the water pump 5.
And S640, if the difference delta 1 is larger than a second preset value A2, increasing the rotating speed of the water pump 5.
Exemplarily, A1= -2, A2=2.
When Δ 1 is less than-2, it means that the water temperature T3 in the second pipeline 42 is less than the target outlet water temperature T0 and has a large difference with the target outlet water temperature, in this case, the rotation speed of the water pump 5 needs to be reduced to slow down the flowing speed of the water, so as to raise the outlet water temperature.
When Δ 1 > 2, it means that the water temperature T3 in the second pipeline 42 is greater than the target outlet water temperature T0 and has a large difference from the target outlet water temperature, in this case, the rotation speed of the water pump 5 needs to be increased to increase the flow speed of the water, thereby reducing the outlet water temperature.
It should be noted that, when the difference Δ 1 between the water temperature T3 in the second pipeline 42 and the target outlet water temperature T0 is between the first preset value A1 and the second preset value A2, it indicates that the actual outlet water temperature is closer to the target outlet water temperature, and in this case, the water pump 5 can be kept at the current rotation speed.
Preferably, as shown in fig. 1, the water purifier of the present invention further includes a preheating tank 6, the preheating tank 6 is communicated with the first pipeline 41, and a connection between the first pipeline 41 and the preheating tank 6 is located between the water pump 5 and the normal-temperature water tank 1.
Illustratively, the preheating tank 6 is provided with a water outlet and a water inlet, wherein the water outlet and the water inlet of the preheating tank 6 are respectively communicated with the first pipeline 41 through a third pipeline 43 and a fourth pipeline 44, the third pipeline 43 and the fourth pipeline 44 are respectively communicated with the first pipeline 41 through a three-way valve 9, the first pipeline 41 is provided with an electric control valve which is denoted as a second electric control valve 82, the second electric control valve 82 is positioned between the two three-way valves 9, and the third pipeline 43 is also provided with an electric control valve which is denoted as a third electric control valve 83.
When the second electric control valve 82 is in an open state and the third electric control valve 83 is in a closed state, the normal-temperature water tank 1 is communicated with the water heating assembly 2, and when the water pump 5 runs, the water in the normal-temperature water tank 1 is pumped into the water heating assembly 2; when the second electric control valve 82 is in a closed state and the third electric control valve 83 is in an open state, the preheating liner water tank 6 is communicated with the water heating assembly 2, and when the water pump 5 runs, the water in the preheating liner water tank 6 is pumped into the water heating assembly 2; when the water in the bladder preheating water tank 6 flows out, the water in the normal temperature water tank 1 automatically flows into the bladder preheating water tank 6 along the fourth pipe 44. A heating member is provided in the preheating tank 6, and the water in the preheating tank 6 can be preheated to keep the water in the preheating tank 6 at a relatively high temperature.
Preferably, the control method of the present invention further comprises: calculating a difference value delta 2 between the target water outlet temperature T0 and the water temperature T2 in the normal-temperature water tank 1; selectively communicating the preheating tank 6 with the water heating assembly 2 according to the difference delta 2. Wherein the difference Δ 2= T0-T2.
Whether the preheating liner water tank 6 is communicated with the water heating assembly 2 or not is judged according to the difference value delta 2 of the target water outlet temperature T0 and the water temperature T2 in the normal-temperature water tank 1, and the situation that the water outlet speed is too low due to too low temperature in the normal-temperature water tank 1 can be avoided.
Specifically, the step of "selectively communicating the preheating liner tank 6 with the water heating unit 2 according to the difference Δ 2" specifically includes: comparing the difference delta 2 with a third preset value A3; if the difference delta 2 is larger than the third preset value A3, the preheating liner water tank 6 is communicated with the water heating assembly 2.
When delta 2 > A3, it indicates that the temperature of water in the normal temperature water tank 1 differs greatly from the target water outlet temperature, and under the condition, if the water in the normal temperature water tank 1 is heated, long heating time is needed, the water flow speed is very slow, the use experience of a user is seriously influenced, the water pump 5 can pump the water in the preheating liner water tank 6 into the water heating assembly 2 to heat the water, so that the water outlet speed is improved, and the preheating liner water tank 6 is communicated with the water heating assembly 2, namely the third electric control valve 83 is opened.
It should be noted that, in practical applications, a person skilled in the art may flexibly set the specific value of the third preset value according to experiments or experience.
