As shown in fig. 2, fig. 2 shows a workflow of a flow rate control method provided by an embodiment of the present invention, where the flow rate control method includes: step 210 to step 240.
Step 210: an input signal is received.
In an embodiment of the invention, the controller may receive an input signal.
In some embodiments, the input signal may be a cold water input signal, a bubble water input signal, or the like.
In some embodiments, the input signal may be generated according to an input operation by a user.
For example, the drinking device may be provided with a touch display screen that may display functions such as a cold water option, a bubble water option, and the like. When the user needs to take cold water from the water drinking device, the user can trigger and generate a cold water input signal by touching the cold water option.

For example, the drinking water equipment can be provided with a cold water button and a bubble water button, and when a user needs to take cold water from the drinking water equipment, the user can trigger and generate a cold water input signal by pressing the cold water button. When a user needs to take bubble water from the drinking water equipment, the user can trigger and generate a bubble water input signal by pressing the bubble water pressing key.
The drinking water device can also be provided with a communication module which can be in communication connection with a terminal of a user so that the user can trigger and generate a cold water input signal and a bubble water input signal through Application software (Application) associated with the drinking water device.
Step 220: a speed signal is determined from the input signal.
Wherein the controller may determine the speed signal upon receiving the input signal.
In some embodiments, the input signal may include an operation signal of a user, the input signal and the rotation speed signal correspond to each other one by one, and the correspondence relationship between the input signal and the rotation speed signal may be preset.
For example, when the input signal is a cold water input signal, the rotating speed signal of the variable frequency water pump can be set to 3000r/min; when the input signal is a bubble water input signal, the initial rotating speed of the variable frequency water pump can be set to 1000r/min.
In other embodiments, the input signal may include a user operation signal and a level detection signal, and the step of step 220 determines the rotation speed signal according to the input signal, including the following steps.
(1) Determining an initial rotation speed according to the operation signal;
the operation signal may be generated according to an input operation of a user, specifically, the touch display screen, the pressed key, the application software, and the like in the foregoing embodiment are not described herein again. Take pressing a key to generate an operation signal as an example. When the user need get cold water from drinking water equipment, then the user can trigger and generate cold water operation signal through pressing the cold water button, when the user needs get bubble water from drinking water equipment, then the user can trigger and generate bubble water operation signal through pressing bubble water button.
The initial rotation speed may be preset according to the requirements. For example, when cold water is taken, the initial rotating speed of the variable frequency water pump can be set to 3000r/min; when bubble water is taken, the initial rotating speed of the variable frequency water pump can be set to 1000r/min.
It should be noted that the value of the initial rotation speed of the up-conversion water pump is only used as an example to facilitate understanding. When a user takes cold water, bubble water or other water, the initial rotating speed of the variable-frequency water pump can be set to be different rotating speeds according to requirements, and can also be set to be the same rotating speed.
(2) If the liquid level detection signal is greater than or equal to the first liquid level threshold and less than or equal to the second liquid level threshold, determining an adjustment rotating speed according to the liquid level detection signal, the second liquid level threshold and the initial rotating speed; wherein the second level threshold is greater than the first level threshold.
Wherein, the liquid level detection signal indicates the liquid level height condition of the water container. The level detection signal may be determined by detecting the water level in the water intake container by an infrared sensor. The liquid level detection signal can also be obtained by arranging a weight sensor at the bottom of the water taking container and determining the liquid level condition of the water taking container through the weight change of the water taking container.
For example, when the infrared sensor detects that the liquid level of the water in the water intake container is 100ml, a liquid level detection signal with the liquid level of 100ml is generated; when the infrared sensor detects that the liquid level of the water in the water intake container is 230ml, a liquid level detection signal with the liquid level of 230ml is generated.
The first liquid level threshold and the second liquid level threshold may be preset according to requirements. For example, the first level threshold may be set to 100ml and the second level threshold may be set to 500ml.
When a user uses the water dispenser to take water, a target liquid level threshold value can be set so that the user can more accurately obtain different water taking amounts. The target liquid level threshold may be generated according to an input operation of a user, such as touching a display screen, pressing a key, and applying software, etc. as in the above embodiments. Taking the input operation as an example of pressing the button, the water dispenser may be provided with water getting buttons with different liquid levels according to actual requirements, for example, the water dispenser may be provided with a 100ml water getting button, a 200ml water getting button, a 300ml water getting button, a 400ml water getting button, a 500ml water getting button, and the like, when the user needs to get 300ml water, the 300ml water getting button is pressed, and the target liquid level threshold is 300ml.
Or, a liquid level key can be arranged on the drinking equipment, and a user can perform superposition by pressing for multiple times. For example, 150ml water getting button is arranged on the drinking equipment, and when the 50ml water getting button is pressed for 1 time, the target liquid level threshold is 50ml; pressing the 50ml water getting button for 2 times, the target liquid level value is 100ml; pressing the 50ml get water button 3 times, the target level value threshold is 150ml, and so on. It can understand ground, also can be provided with the water intaking button of a plurality of different liquid levels on the drinking water equipment to the user can be through pressing different water intaking buttons in order to superpose the water intaking volume, thereby can obtain required water intaking volume more accurately.
It is understood that the second level threshold may also be used as the target level threshold, for example, when the target level threshold is set to 400ml, the second level threshold is 400ml.
In some embodiments, the step of determining the adjusted rotational speed based on the level detection signal, the second level threshold, and the initial rotational speed comprises the following steps.
(2.1) determining a liquid level difference value according to the liquid level detection signal and a second liquid level threshold value;
(2.2) determining an adjusting rotating speed according to the liquid level difference value and the initial rotating speed; wherein, the smaller the liquid level difference value is, the larger the adjusting rotating speed is; when the liquid level difference is zero, adjusting the rotating speed to be equal to the initial rotating speed;
wherein, the relation between liquid level difference and the adjustment rotational speed can be preset according to actual demand. For example, taking cold water as an example, the initial rotation speed of the variable frequency water pump can be set to 3000r/min. When the liquid level difference is 0ml, correspondingly adjusting the rotating speed to 3000r/min; when the liquid level difference is 50ml, correspondingly adjusting the rotating speed to be 2500r/min; when the liquid level difference is 100ml, correspondingly adjusting the rotating speed to 2000r/min; when the liquid level difference is 150ml, correspondingly adjusting the rotating speed to be 1500r/min; when the liquid level difference is 200ml, correspondingly adjusting the rotating speed to be 1000r/min; when the liquid level difference is 250ml, the corresponding adjustment rotating speed is 500r/min.
Specifically, when a user uses a 500ml cup to draw cold water, the first level threshold is set to 100ml and the second level threshold is set to 400ml. When the liquid level detection signal detects that the water in the water cup is 150ml, the liquid level difference value between the liquid level detection signal and the second liquid level threshold value is 250ml, and the adjusting rotating speed is determined to be 500r/min according to the corresponding relation between the liquid level difference value and the adjusting rotating speed.
When the liquid level detection signal detects that the water in the water cup is 300ml, the difference value between the liquid level detection signal and the second liquid level threshold value is 100ml, and the adjusting rotating speed is determined to be 2000r/min according to the corresponding relation between the liquid level difference value and the adjusting rotating speed.
When the liquid level detection signal detects that the water in the water cup is 400ml, the difference value between the liquid level detection signal and the second liquid level threshold value is 0ml, and the adjusting rotating speed is determined to be 3000r/min according to the corresponding relation between the liquid level difference value and the adjusting rotating speed, namely the adjusting rotating speed is equal to the initial rotating speed.
(3) And determining a rotation speed signal according to the initial rotation speed and the adjusted rotation speed.
In some embodiments, the step of determining a speed signal based on the initial speed and the adjusted speed comprises: and determining a rotation speed signal according to the difference value of the initial rotation speed and the adjusted rotation speed.
According to the above example, if the initial rotation speed of the variable frequency water pump is set to 3000r/min, then:
when the liquid level difference is 250ml, the adjusting rotating speed is 500r/min, and the rotating speed difference between the initial rotating speed and the adjusting rotating speed is 2500r/min, the rotating speed signal is determined to be 2500r/min.
When the liquid level difference is 200ml, the adjusting rotating speed is 1000r/min, the rotating speed difference between the initial rotating speed and the adjusting rotating speed is 2000r/min, and the rotating speed signal is determined to be 2000r/min.
When the liquid level difference is 150ml, the adjusting rotating speed is 1500r/min, and the rotating speed difference between the initial rotating speed and the adjusting rotating speed is 1500r/min, the rotating speed signal is determined to be 1500r/min.
When the liquid level difference is 100ml, the adjusting rotating speed is 2000r/min, and the rotating speed difference between the initial rotating speed and the adjusting rotating speed is 1000r/min, the rotating speed signal is determined to be 1000r/min.
When the liquid level difference is 0ml, the adjusting rotating speed is 3000r/min, and the rotating speed difference between the initial rotating speed and the adjusting rotating speed is 0r/min, the rotating speed signal is determined to be 0r/min.
It is understood that when the liquid level detection signal is between the first liquid level threshold and the second liquid level threshold, the larger the liquid level difference, the smaller the adjustment rotation speed, and the larger the corresponding rotation speed signal. When the liquid level difference value is smaller, the adjusting rotating speed is larger, and the corresponding rotating speed signal is smaller.
Thus, the rotation speed signal is smaller as the water level is closer to the second liquid level threshold; when the water level equals the second liquid level threshold, the rotational speed signal is zero, and the play water velocity of flow is zero promptly, and at this moment, drinking water equipment stops out water, can accurate output user's required water yield.
Step 230: and determining a speed regulating signal according to the rotating speed signal.
The variable frequency water pump can be used for determining a speed regulating signal according to the rotating speed signal.
In some embodiments, the step of determining a throttle signal from the speed signal in step 230 includes:
and determining a speed regulating signal corresponding to the rotating speed signal based on a preset corresponding relation, wherein the preset corresponding relation comprises different corresponding relations between the rotating speed signal and the speed regulating signal.
As an example, in the preset corresponding relationship, the rotation speed signal is 0r/min, and the corresponding speed regulating signal is 0V; when the rotating speed signal is 500r/min, the corresponding speed regulating signal is 1V; when the rotating speed signal is 1000r/min, the corresponding speed regulating signal is 2V, and when the rotating speed signal is 1500r/min, the corresponding speed regulating signal is 3V; when the rotating speed signal is 2000r/min, the corresponding speed regulating signal is 4V; when the rotating speed signal is 2500r/min, the corresponding speed regulating signal is 5V; when the rotating speed signal is 3000r/min, the corresponding speed regulating signal is 6V, and the like.
If the initial rotating speed of the variable frequency water pump is set to 3000r/min, then:
when the rotating speed signal is 0r/min, according to the preset corresponding relation, the variable frequency water pump determines that the speed regulating signal is 0V, and the variable frequency water pump operates at the rotating speed of 0r/min, namely the variable frequency water pump stops operating.
And when the rotating speed signal is 500r/min, the variable frequency water pump determines that the speed regulating signal is 1V according to the preset corresponding relation, and the variable frequency water pump operates at the rotating speed of 500r/min.
And when the rotating speed signal is 1000r/min, determining that the speed regulating signal is 2V by the variable-frequency water pump according to the preset corresponding relation, and operating the variable-frequency water pump at the rotating speed of 1000r/min.
When the rotating speed signal is 1500r/min, according to the preset corresponding relation, the variable frequency water pump determines that the speed regulating signal is 3V, and the variable frequency water pump operates at the rotating speed of 1500r/min;
when the rotating speed signal is 2000r/min, the variable frequency water pump determines that the speed regulating signal is 4V according to the preset corresponding relation, and the variable frequency water pump operates at the rotating speed of 2000r/min.
When the rotating speed signal is 2500r/min, the variable frequency water pump determines that the speed regulating signal is 5V according to the preset corresponding relation, and the variable frequency water pump operates at the rotating speed of 2500r/min.
And when the rotating speed signal is 3000r/min, the variable frequency water pump determines that the speed regulating signal is 6V according to the preset corresponding relation, and the variable frequency water pump runs at the rotating speed of 3000r/min.
It will be appreciated that the greater the speed signal, the greater the throttle signal. If the rotating speed signal is smaller, the speed regulating signal is smaller.
In some embodiments, the step of determining a throttle signal from the speed signal in step 230 includes the following steps.
(1) Determining a rotation speed difference value according to the rotation speed signal and the real-time rotation speed;
(2) And determining a speed regulating signal according to the rotation speed difference.
The corresponding relation between the rotating speed difference and the speed regulating signal can be preset.
As an example, when the rotation speed difference is 0r/min, the corresponding speed regulating signal is 0V; when the difference value of the rotating speeds is 500r/min, the corresponding speed regulating signal is 1V; when the difference value of the rotating speeds is 1000r/min, the corresponding speed regulating signal is 2V; when the difference value of the rotating speeds is 1500r/min, the corresponding speed regulating signal is 3V; when the rotating speed difference is 2000r/min, the corresponding speed regulating signal is 4V, and the like.
Wherein, if the real-time rotational speed of frequency conversion water pump is 500r/min, then:
when the rotating speed signal is 500r/min, the rotating speed difference value between the rotating speed signal and the real-time rotating speed is 0r/min, the speed regulating signal is determined to be 0V, the variable frequency water pump is overlapped with 0r/min on the basis that the real-time rotating speed is 500r/min, and the rotating speed of the variable frequency water pump after the variable frequency water pump obtains the 0V speed regulating signal is kept unchanged at 500r/min.
When the rotating speed signal is 1000r/min, the rotating speed difference value between the rotating speed signal and the real-time rotating speed is 500r/min, the speed regulating signal is determined to be 1V, the variable frequency water pump is overlapped with 500r/min on the basis that the real-time rotating speed is 500r/min, and the rotating speed of the variable frequency water pump after obtaining the 1V speed regulating signal is 1000r/min.
When the rotating speed signal is 1500r/min, the rotating speed difference value between the rotating speed signal and the real-time rotating speed is 1000r/min, the speed regulating signal is determined to be 2V, the variable frequency water pump is superposed with 1000r/min on the basis that the real-time rotating speed is 500r/min, and the rotating speed of the variable frequency water pump after the variable frequency water pump obtains the 2V speed regulating signal is 1500r/min.
When the rotating speed signal is 2000r/min, the rotating speed difference value between the rotating speed signal and the real-time rotating speed is 1500r/min, the speed regulating signal is determined to be 3V, the variable frequency water pump is overlapped with 1500r/min on the basis that the real-time rotating speed is 500r/min, and the rotating speed of the variable frequency water pump after the variable frequency water pump obtains the 3V speed regulating signal is 2000r/min.
When the rotating speed signal is 2500r/min, the rotating speed difference value between the rotating speed signal and the real-time rotating speed is 2000r/min, the speed regulating signal is determined to be 4V, the rotating speed of the variable-frequency water pump is 2500r/min after the variable-frequency water pump obtains the 2V speed regulating signal after the variable-frequency water pump is superposed with 2000r/min on the basis that the real-time rotating speed is 500r/min.
It can be understood that if the rotation speed signal is larger, the rotation speed difference value is larger, and the corresponding speed regulation signal is larger. If the rotating speed signal is smaller, the rotating speed difference value is smaller, and the speed regulating signal is smaller.
Step 240: and adjusting the rotating speed of the variable-frequency water pump according to the speed regulating signal.
The variable frequency water pump can be used for adjusting the rotating speed of the variable frequency water pump according to the speed regulation signal. For example, the variable frequency water pump may include a variable frequency drive. And after receiving the speed regulating signal, the frequency converter regulates the rotating speed of the variable-frequency water pump.
As an example, the frequency converter may determine a speed regulation signal corresponding to the rotation speed signal based on a preset correspondence, so as to adjust the rotation speed of the variable frequency water pump.
Specifically, when the rotating speed signal is 0r/min and the corresponding speed regulating signal is 0V, the rotating speed of the variable frequency water pump is 0r/min, and the variable frequency water pump stops running; when the rotating speed signal is 500r/min, the corresponding speed regulating signal is 1V, and the rotating speed of the variable frequency water pump is 500r/min; when the rotating speed signal is 1000r/min, the corresponding speed regulating signal is 2V, and the rotating speed of the variable frequency water pump is 1000r/min; when the rotating speed signal is 1500r/min, the corresponding speed regulating signal is 3V, and the rotating speed of the variable frequency water pump is 1500r/min; when the rotating speed signal is 2000r/min, the corresponding speed regulating signal is 4V, and the rotating speed of the variable frequency water pump is 2000r/min; when the rotating speed signal is 2500r/min, the corresponding speed regulating signal is 5V, and the rotating speed of the variable frequency water pump is 2500r/min; when the rotating speed signal is 3000r/min, the corresponding speed regulating signal is 6V, the rotating speed of the variable frequency water pump is 3000r/min, and the like.
As another example, the frequency converter may further determine a rotation speed difference according to the rotation speed signal and the real-time rotation speed, and then determine a speed regulation signal according to the rotation speed difference, so as to adjust the rotation speed of the variable frequency water pump.
Specifically, if the real-time rotation speed is 500r/min. When the rotating speed difference value is 0r/min, the corresponding speed regulating signal is 0V, and the rotating speed of the variable frequency water pump is kept at 500r/min; when the difference value of the rotating speeds is 500r/min, the corresponding speed regulating signal is 1V, and the rotating speed of the variable frequency water pump is regulated to 1000r/min; when the difference value of the rotating speeds is 1000r/min, the corresponding speed regulating signal is 2V, and the rotating speed of the variable frequency water pump is adjusted to 1500r/min; when the rotating speed difference value is 1500r/min, the corresponding speed regulating signal is 3V, and the rotating speed of the variable frequency water pump is regulated to 2000r/min; when the rotating speed difference is 2000r/min, the corresponding speed regulating signal is 4V, the rotating speed of the variable frequency water pump is regulated to 2500r/min, and the like.

As an example, when a user draws cold water using a 500ml water intake vessel, the first level threshold is set to 100ml and the initial speed of the variable frequency water pump is 3000r/min. When the liquid level detection signal detects that the water in the water taking container is 50ml, the liquid level detection signal is smaller than a first liquid level threshold value, and the rotating speed signal is determined to be 3000r/min.
