[0017] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0018] A water pump (such as a diaphragm pump, a booster pump, etc.) is usually installed in the drinking water equipment to increase the water pressure of the water system in the drinking water equipment.

[0019] As the functions of drinking water equipment become increasingly complex, different functions have different requirements for water flow rates, resulting in the need to use multiple water pumps to meet multi-functional water intake needs when using different functions of drinking water equipment, making the cost of drinking water equipment high, the size large, and the production complicated.

[0020] For example, current drinking water equipment has multiple water dispensing functions such as cold water, sparkling water, boiling water, boiled water, and warm water. Different functions require different flow rates. Specifically, when a user takes cold water, if the water flow rate is slow, it is easy to cause the water dispensing time to be too long; when a user takes bubbles, if the water flow rate is too fast, it is easy to affect the gas content of the sparkling water; when a user takes boiled water, if the water flow rate is too fast, it is easy to cause water splashing, and the user is easy to be scalded by the splashing boiled water.

[0021] In order to improve the above-mentioned problems, the inventors have proposed the flow rate control method, device, drinking water equipment and storage medium provided by the present invention. The method is applied to drinking water equipment with a variable frequency water pump, and the method includes: receiving an input signal; determining a speed signal according to the input signal; determining a speed regulation signal according to the speed signal; and adjusting the speed of the variable frequency water pump according to the speed regulation signal. The present invention sets a variable frequency water pump in the drinking water equipment, determines a speed signal according to the input signal, and then determines the speed regulation signal according to the speed signal, so that the speed of the variable frequency water pump can be adjusted according to demand. The drinking water equipment can adjust different water outlet flow rates through the variable frequency water pump, so that the drinking water equipment can meet multi-functional water intake needs, reduce the number of water pumps used, thereby reducing the manufacturing cost of the drinking water equipment, reducing the volume of the drinking water equipment, and simplifying the production process of the drinking water equipment.

[0022] The following introduces the application environment of the flow rate control method provided by the embodiment of the present invention.

[0023] See also Figure 1 The flow rate control method provided in the embodiment of the present invention can be applied to drinking water equipment with a variable frequency water pump.

[0024] The drinking water device 100 may be a water dispenser, a water purifier, a water purifier and a drinking water purifier, etc. The embodiment of the present invention is explained by taking a water dispenser as an example, and the water dispenser may have a variety of water dispensing functions such as cold water, sparkling water, boiled water, boiled water, warm water, etc. For ease of description, the following explanation is given by taking a water dispenser having cold water and sparkling water functions as an example.

[0025] The drinking water device 100 may include a controller 110 and a variable frequency water pump 120. The controller 110 may be used to receive an input signal and determine a speed signal according to the input signal; the variable frequency water pump 120 may be used to determine a speed regulation signal according to the speed signal and adjust the speed of the variable frequency water pump 120 according to the speed regulation signal.

[0026] In some embodiments, the drinking water equipment 100 may further include an inlet pipe, an outlet pipe, an inlet valve, and an outlet valve. The inlet pipe is connected to the water inlet end of the variable frequency water pump 120 and the water source, respectively, the inlet valve is connected to the inlet pipe, and controls the on-off of the water path. The outlet pipe is connected to the water outlet end of the variable frequency water pump 120 and the water outlet device, respectively, the outlet valve is connected to the outlet pipe, and controls the on-off of the water path. The water outlet device may be a faucet.

[0027] In some embodiments, the drinking water equipment 100 may include one water outlet pipe, or may include multiple water outlet pipes. When the drinking water equipment 100 includes multiple water outlet pipes, the number of water outlet valves is equal to the number of water outlet pipes, and each water outlet pipe is connected to a water outlet valve.

[0028] In some embodiments, the input signal may be generated according to a user input operation, such as touching a display screen, pressing a button, and application software, etc. The input signal may be a cold water input signal, a bubble water input signal, a hot water input signal, and the like.

[0029] In some embodiments, the drinking water equipment 100 may further include a water intake device, and the water intake device may be connected to the water inlet valve and the water outlet valve.

[0030] Optionally, the water intake device may be a button, a touch screen, etc. For ease of description, the water intake device is a button, the drinking water device 100 includes two water outlet pipes and two water outlet valves, the two water outlet pipes are respectively a first water outlet pipe and a second water outlet pipe, and the two water outlet valves are respectively a first water outlet valve and a second water outlet valve.

[0031] For example, the drinking water device 100 may include a cold water dispensing button and a bubble water dispensing button, wherein the cold water dispensing button is connected to the water inlet valve and the first water outlet valve respectively; and the bubble water dispensing button is connected to the water inlet valve and the second water outlet valve respectively. When the cold water dispensing button is pressed, a cold water input signal is generated, the water inlet valve and the first water outlet valve are connected to the water path, the controller 110 determines the speed signal after receiving the cold water input signal, the variable frequency water pump 120 determines the speed regulation signal according to the speed signal, the variable frequency water pump 120 adjusts its own speed according to the speed regulation signal, and the variable frequency water pump 120 outputs cold water at a first flow rate, and the cold water flows out of the water nozzle through the first water outlet pipe.

[0032] When the bubble water dispensing button is pressed, a bubble water input signal is generated, the water inlet valve and the second water outlet valve are connected to the water path, the controller 110 determines the speed signal after receiving the bubble water input signal, the variable frequency water pump 120 determines the speed regulation signal according to the speed signal, the variable frequency water pump 120 adjusts its own speed according to the speed regulation signal, the variable frequency water pump 120 outputs bubble water at the second flow rate, and the bubble water flows out of the water nozzle through the second water outlet pipe. The first flow rate and the second flow rate can be distinguished.

[0033] In some embodiments, the water outlet valve can also be adjusted manually to control the on-off of the water path.

[0034] In some embodiments, the variable frequency water pump 120 may include: a water pump control unit 121 and a water pump variable frequency unit 122 .

[0035] The water pump control unit 121 may be used to determine the speed regulation signal according to the speed signal. The water pump control unit 121 may receive the speed signal sent by the controller 110 and determine the speed regulation signal according to the speed signal.

[0036] The water pump frequency conversion unit 122 can be used to adjust the speed of the water pump frequency conversion unit 122 according to the speed regulation signal. For example, the water pump frequency conversion unit 122 can be a frequency converter, and the frequency converter controls the speed of the variable frequency water pump 120 after receiving the speed regulation signal, so that the variable frequency water pump 120 can adjust its own speed according to the speed regulation signal to output water with different flow rates, so that the drinking water device 100 can meet the multi-functional water intake demand.

[0037] In some embodiments, the controller 110 can also be used to generate a power supply signal when receiving an input signal. The drinking water equipment 100 can also include a power module 130, which can be connected to the controller 110 and the water pump frequency conversion unit 122 respectively, and the power module 130 can be used to control the variable frequency water pump 120 to work at a preset speed according to the power supply signal. For example, the power module 130 can provide a stable power supply for the variable frequency water pump 120, so that the power module 130 can control the variable frequency water pump 120 to work at a preset speed according to the power supply signal.

[0038] In this way, the variable frequency water pump 120 can adjust its own rotation speed through the speed regulation signal to achieve a variety of different water outlet flow rates, so that the drinking water equipment 100 can meet the multi-functional water intake needs, reducing the number of water pumps used, thereby reducing the manufacturing cost of the drinking water equipment 100, reducing the volume of the drinking water equipment 100, and simplifying the production process of the drinking water equipment 100, which will be explained in detail in the following embodiments.

[0039] like Figure 2 As shown, Figure 2The flow rate control method provided in the embodiment of the present invention is shown as a workflow, and the flow rate control method includes: step 210 to step 240.

[0040] Step 210: Receive an input signal.

[0041] In an embodiment of the present invention, the controller may receive an input signal.

[0042] In some embodiments, the input signal may be a cold water input signal, a bubble water input signal, or the like.

[0043] In some implementations, the input signal may be generated according to an input operation of a user.

[0044] For example, the drinking water device may be provided with a touch screen, and the touch screen may display functions such as a cold water option and a sparkling water option. When the user needs to take cold water from the drinking water device, the user may touch the cold water option to trigger and generate a cold water input signal. When the user needs to take sparkling water from the drinking water device, the user may touch the sparkling water option to trigger and generate a sparkling water input signal.

[0045] In addition to obtaining user input operations by setting a touch display screen, the drinking water device can also obtain user input operations by setting buttons. For example, the drinking water device can be provided with a cold water button and a sparkling water button. When the user needs to take cold water from the drinking water device, the user can trigger and generate a cold water input signal by pressing the cold water button. When the user needs to take sparkling water from the drinking water device, the user can trigger and generate a sparkling water input signal by pressing the sparkling water button.

[0046] The drinking water device may also be provided with a communication module, which may be connected to a user's terminal for communication, so that the user may trigger and generate a cold water input signal and a bubble water input signal through an application software associated with the drinking water device.

[0047] Step 220: Determine a speed signal according to the input signal.

[0048] The controller may determine a rotation speed signal after receiving an input signal.

[0049] In some implementations, the input signal may include an operation signal of a user, and the input signal corresponds to the rotation speed signal one-to-one, and the corresponding relationship between the input signal and the rotation speed signal may be preset.

[0050] For example, when the input signal is a cold water input signal, the 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 speed of the variable frequency water pump can be set to 1000r / min.

[0051] In other embodiments, the input signal may include a user's operation signal and a liquid level detection signal, and the steps in step 220 determine the rotation speed signal according to the input signal, including the following steps.

[0052] (1) Determine the initial speed according to the operating signal;

[0053] The operation signal can be generated according to the user's input operation, such as the touch screen, pressing buttons, and application software in the above-mentioned embodiments, which will not be described in detail here. Take the generation of the operation signal by pressing a button as an example. When the user needs to take cold water from the drinking water device, the user can press the cold water button to trigger and generate the cold water operation signal. When the user needs to take sparkling water from the drinking water device, the user can press the sparkling water button to trigger and generate the sparkling water operation signal.

[0054] The initial speed can be preset according to the demand. For example, when taking cold water, the initial speed of the variable frequency water pump can be set to 3000r / min; when taking sparkling water, the initial speed of the variable frequency water pump can be set to 1000r / min.

[0055] It should be noted that the above values ​​of the initial speed of the variable frequency water pump are only used as an example for ease of understanding. When the user takes cold water, sparkling water or other water, the initial speed of the variable frequency water pump can be set to different speeds according to needs, or it can be set to the same speed.

[0056] (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, the adjustment speed is determined based on the liquid level detection signal, the second liquid level threshold and the initial speed; wherein the second liquid level threshold is greater than the first liquid level threshold.

[0057] The liquid level detection signal represents the liquid level in the water collection container. The liquid level detection signal can be determined by detecting the water level in the water collection container through an infrared sensor. The liquid level detection signal can also be determined by setting a weight sensor at the bottom of the water collection container and determining the liquid level in the water collection container through the weight change of the water collection container.

[0058] For example, when the infrared sensor detects that the water level in the water collection container is 100 ml, it generates a liquid level detection signal of 100 ml; when the infrared sensor detects that the water level in the water collection container is 230 ml, it generates a liquid level detection signal of 230 ml.

[0059] The first liquid level threshold and the second liquid level threshold can be preset according to requirements. For example, the first liquid level threshold can be set to 100 ml, and the second liquid level threshold can be set to 500 ml.

[0060] When a user uses a drinking water device to draw water, a target liquid level threshold can be set so that the user can obtain different water intake amounts more accurately. The target liquid level threshold can be generated according to the user's input operation, such as touching the display screen, pressing buttons, and application software in the above-mentioned implementation. Taking the input operation of pressing a button as an example, the drinking water device can be provided with water intake buttons of different liquid levels according to actual needs. For example, the drinking water device can be provided with a 100ml water intake button, a 200ml water intake button, a 300ml water intake button, a 400ml water intake button, a 500ml water intake button, etc. When the user needs to take 300ml of water, press the 300ml water intake button, and the target liquid level threshold is 300ml.

[0061] Alternatively, a liquid level button can be provided on the drinking water device, and the user can add up the liquid level by pressing it multiple times. For example, a 50ml water dispensing button is provided on the drinking water device. If the 50ml water dispensing button is pressed once, the target liquid level threshold is 50ml; if the 50ml water dispensing button is pressed twice, the target liquid level value is 100ml; if the 50ml water dispensing button is pressed three times, the target liquid level value threshold is 150ml, and so on. It can be understood that a plurality of water dispensing buttons with different liquid levels can also be provided on the drinking water device, so that the user can add up the water dispensing amount by pressing different water dispensing buttons, so as to obtain the required water dispensing amount more accurately.

[0062] It can be understood that the second liquid level threshold can also be used as the target liquid level threshold. For example, when the target liquid level threshold is set to 400 ml, the second liquid level threshold is 400 ml.

[0063] In some embodiments, the step of determining the adjusted rotation speed according to the liquid level detection signal, the second liquid level threshold and the initial rotation speed comprises the following steps.

[0064] (2.1) determining a liquid level difference according to a liquid level detection signal and a second liquid level threshold;

[0065] (2.2) Determine the adjustment speed according to the liquid level difference and the initial speed; wherein, the smaller the liquid level difference, the greater the adjustment speed; when the liquid level difference is zero, the adjustment speed is equal to the initial speed;

[0066] Among them, the relationship between the liquid level difference and the adjustment speed can be preset according to actual needs. For example, taking cold water as an example, the initial speed of the variable frequency water pump can be set to 3000r / min. When the liquid level difference is 0ml, the corresponding adjustment speed is 3000r / min; when the liquid level difference is 50ml, the corresponding adjustment speed is 2500r / min; when the liquid level difference is 100ml, the corresponding adjustment speed is 2000r / min; when the liquid level difference is 150ml, the corresponding adjustment speed is 1500r / min; when the liquid level difference is 200ml, the corresponding adjustment speed is 1000r / min; when the liquid level difference is 250ml, the corresponding adjustment speed is 500r / min.

[0067] Specifically, when the user uses a 500ml water cup to take cold water, the first liquid level threshold is set to 100ml, and the second liquid 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 between the liquid level detection signal and the second liquid level threshold is 250ml. According to the corresponding relationship between the above liquid level difference and the adjustment speed, the adjustment speed is determined to be 500r / min.

[0068] When the liquid level detection signal detects that the water in the cup is 300 ml, the difference between the liquid level detection signal and the second liquid level threshold is 100 ml. According to the corresponding relationship between the above liquid level difference and the adjustment speed, the adjustment speed is determined to be 2000 r / min.

[0069] When the liquid level detection signal detects that the water in the cup is 400ml, the difference between the liquid level detection signal and the second liquid level threshold is 0ml. According to the corresponding relationship between the above liquid level difference and the adjustment speed, the adjustment speed is determined to be 3000r / min, that is, the adjustment speed is equal to the initial speed.

[0070] (3) Determine the speed signal based on the initial speed and the adjusted speed.

[0071] In some embodiments, the step of determining the rotation speed signal according to the initial rotation speed and the adjusted rotation speed includes: determining the rotation speed signal according to a difference between the initial rotation speed and the adjusted rotation speed.

[0072] According to the above example, if the initial speed of the variable frequency water pump is set to 3000r / min, then:

[0073] When the liquid level difference is 250ml, the speed is adjusted to 500r / min, and the speed difference between the initial speed and the adjusted speed is 2500r / min, so the speed signal is determined to be 2500r / min.

[0074] When the liquid level difference is 200ml, the speed is adjusted to 1000r / min, and the speed difference between the initial speed and the adjusted speed is 2000r / min, so the speed signal is determined to be 2000r / min.

[0075] When the liquid level difference is 150ml, the speed is adjusted to 1500r / min. The speed difference between the initial speed and the adjusted speed is 1500r / min, so the speed signal is determined to be 1500r / min.

[0076] When the liquid level difference is 100ml, the speed is adjusted to 2000r / min, and the speed difference between the initial speed and the adjusted speed is 1000r / min, so the speed signal is determined to be 1000r / min.

[0077] When the liquid level difference is 0ml, the speed is adjusted to 3000r / min, and the speed difference between the initial speed and the adjusted speed is 0r / min, then the speed signal is determined to be 0r / min.

[0078] It can be 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 speed, and the larger the corresponding speed signal. When the liquid level difference is smaller, the adjustment speed is larger, and the corresponding speed signal is smaller.

[0079] Therefore, the closer the water level is to the second liquid level threshold, the smaller the speed signal is; when the water level is equal to the second liquid level threshold, the speed signal is zero, that is, the water flow rate is zero. At this time, the drinking water equipment stops discharging water and can accurately output the amount of water required by the user.

[0080] Step 230: Determine a speed control signal according to the speed signal.

[0081] The variable frequency water pump can be used to determine the speed regulation signal according to the speed signal.

[0082] In some implementations, the step of determining the speed control signal according to the speed signal in step 230 includes:

[0083] A speed regulation signal corresponding to the rotational speed signal is determined based on a preset corresponding relationship, wherein the preset corresponding relationship includes different corresponding relationships between the rotational speed signal and the speed regulation signal.

[0084] As an example, in the preset corresponding relationship, when the speed signal is 0r / min, the corresponding speed regulation signal is 0V; when the speed signal is 500r / min, the corresponding speed regulation signal is 1V; when the speed signal is 1000r / min, the corresponding speed regulation signal is 2V; when the speed signal is 1500r / min, the corresponding speed regulation signal is 3V; when the speed signal is 2000r / min, the corresponding speed regulation signal is 4V; when the speed signal is 2500r / min, the corresponding speed regulation signal is 5V; when the speed signal is 3000r / min, the corresponding speed regulation signal is 6V, and so on.

[0085] Among them, if the initial speed of the variable frequency water pump is set to 3000r / min, then:

[0086] When the speed signal is 0r / min, according to the preset corresponding relationship, the variable frequency water pump determines that the speed regulation signal is 0V, and the variable frequency water pump runs at a speed of 0r / min, that is, the variable frequency water pump stops running.

[0087] When the speed signal is 500r / min, according to the preset corresponding relationship, the variable frequency water pump determines that the speed regulation signal is 1V, and the variable frequency water pump runs at a speed of 500r / min.

[0088] When the speed signal is 1000r / min, according to the preset corresponding relationship, the variable frequency water pump determines that the speed regulation signal is 2V, and the variable frequency water pump runs at a speed of 1000r / min.

[0089] When the speed signal is 1500r / min, according to the preset corresponding relationship, the variable frequency water pump determines that the speed regulation signal is 3V, and the variable frequency water pump runs at a speed of 1500r / min;

[0090] When the speed signal is 2000r / min, according to the preset corresponding relationship, the variable frequency water pump determines that the speed regulation signal is 4V, and the variable frequency water pump runs at a speed of 2000r / min.

[0091] When the speed signal is 2500r / min, according to the preset corresponding relationship, the variable frequency water pump determines that the speed regulation signal is 5V, and the variable frequency water pump runs at a speed of 2500r / min.

[0092] When the speed signal is 3000r / min, according to the preset corresponding relationship, the variable frequency water pump determines that the speed regulation signal is 6V, and the variable frequency water pump runs at a speed of 3000r / min.

[0093] It can be understood that if the speed signal is larger, the speed regulation signal is larger, and if the speed signal is smaller, the speed regulation signal is smaller.

[0094] In some implementations, the step of determining the speed control signal according to the speed signal in step 230 includes the following steps.

[0095] (1) Determine the speed difference based on the speed signal and the real-time speed;

[0096] (2) Determine the speed control signal based on the speed difference.

[0097] The corresponding relationship between the speed difference and the speed regulation signal can be preset.

[0098] As an example, when the speed difference is 0r / min, the corresponding speed regulation signal is 0V; when the speed difference is 500r / min, the corresponding speed regulation signal is 1V; when the speed difference is 1000r / min, the corresponding speed regulation signal is 2V; when the speed difference is 1500r / min, the corresponding speed regulation signal is 3V; when the speed difference is 2000r / min, the corresponding speed regulation signal is 4V, and so on.

[0099] Among them, if the real-time speed of the variable frequency water pump is 500r / min, then:

[0100] When the speed signal is 500r / min, the speed difference between the speed signal and the real-time speed is 0r / min, then the speed regulation signal is determined to be 0V, and the variable frequency water pump superimposes 0r / min on the real-time speed of 500r / min. After the variable frequency water pump obtains the 0V speed regulation signal, the speed remains unchanged at 500r / min.

[0101] When the speed signal is 1000r / min, the speed difference between the speed signal and the real-time speed is 500r / min, then the speed regulation signal is determined to be 1V, and the variable frequency water pump superimposes 500r / min on the real-time speed of 500r / min. Then the speed of the variable frequency water pump after obtaining the 1V speed regulation signal is 1000r / min.

[0102] When the speed signal is 1500r / min, the speed difference between the speed signal and the real-time speed is 1000r / min, then the speed regulation signal is determined to be 2V. The variable frequency water pump superimposes 1000r / min on the real-time speed of 500r / min. After the variable frequency water pump obtains the 2V speed regulation signal, the speed is 1500r / min.

[0103] When the speed signal is 2000r / min, the speed difference between the speed signal and the real-time speed is 1500r / min, then the speed regulation signal is determined to be 3V. The variable frequency water pump superimposes 1500r / min on the real-time speed of 500r / min, and the speed of the variable frequency water pump after obtaining the 3V speed regulation signal is 2000r / min.

[0104] When the speed signal is 2500r / min, the speed difference between the speed signal and the real-time speed is 2000r / min, then the speed regulation signal is determined to be 4V, and the variable frequency water pump superimposes 2000r / min on the real-time speed of 500r / min. After the variable frequency water pump obtains the 2V speed regulation signal, the speed is 2500r / min.

[0105] It can be understood that if the speed signal is larger, the speed difference is larger, and the corresponding speed regulation signal is larger. If the speed signal is smaller, the speed difference is smaller, and the speed regulation signal is smaller.

[0106] Step 240: Adjust the speed of the variable frequency water pump according to the speed regulation signal.

[0107] The variable frequency water pump can be used to adjust its own speed according to the speed regulation signal. For example, the variable frequency water pump can include a frequency converter. After receiving the speed regulation signal, the frequency converter adjusts the speed of the variable frequency water pump.

[0108] As an example, the frequency converter may determine a speed regulation signal corresponding to the speed signal based on a preset corresponding relationship, thereby adjusting the speed of the variable frequency water pump.

[0109] Specifically, when the speed signal is 0r / min, the corresponding speed regulation signal is 0V, then the speed of the variable frequency water pump is 0r / min, and the variable frequency water pump stops running; when the speed signal is 500r / min, the corresponding speed regulation signal is 1V, then the speed of the variable frequency water pump is 500r / min; when the speed signal is 1000r / min, the corresponding speed regulation signal is 2V, then the speed of the variable frequency water pump is 1000r / min; when the speed signal is 1500r / min, the corresponding speed regulation signal is 2V, then the speed of the variable frequency water pump is 1500r / min. When the speed signal is 3V, the speed of the variable frequency water pump is 1500r / min; when the speed signal is 2000r / min, the corresponding speed regulation signal is 4V, the speed of the variable frequency water pump is 2000r / min; when the speed signal is 2500r / min, the corresponding speed regulation signal is 5V, the speed of the variable frequency water pump is 2500r / min; when the speed signal is 3000r / min, the corresponding speed regulation signal is 6V, the speed of the variable frequency water pump is 3000r / min, and so on.

[0110] As another example, the frequency converter may also determine a speed difference according to the speed signal and the real-time speed, and then determine a speed regulation signal according to the speed difference, thereby adjusting the speed of the variable frequency water pump.

[0111] Specifically, if the real-time speed is 500r / min. When the speed difference is 0r / min, the corresponding speed regulation signal is 0V, and the speed of the variable frequency water pump is maintained at 500r / min; when the speed difference is 500r / min, the corresponding speed regulation signal is 1V, and the speed of the variable frequency water pump is adjusted to 1000r / min; when the speed difference is 1000r / min, the corresponding speed regulation signal is 2V, and the speed of the variable frequency water pump is adjusted to 1500r / min; when the speed difference is 1500r / min, the corresponding speed regulation signal is 3V, and the speed of the variable frequency water pump is adjusted to 2000r / min; when the speed difference is 2000r / min, the corresponding speed regulation signal is 4V, and the speed of the variable frequency water pump is adjusted to 2500r / min, and so on.

[0112] In some implementations, the flow rate control method provided by the embodiment of the present invention may further include the step of: if the liquid level detection signal is less than the first liquid level threshold, determining the rotation speed signal according to the initial rotation speed.

[0113] As an example, when a user uses a 500ml water container to take cold water, the first liquid 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 container is 50ml, the liquid level detection signal is less than the first liquid level threshold, and the speed signal is determined to be 3000r / min.

[0114] In some implementations, the flow rate control method provided by the embodiment of the present invention may further include the following steps.

[0115] (1) When receiving an input signal, a power supply signal is generated.

[0116] (2) According to the power supply signal, the variable frequency water pump is controlled to operate at a preset speed.

[0117] The preset speed of the variable frequency water pump can be preset according to demand. For example, the preset speed of the variable frequency water pump can be preset to 500r / min, 1000r / min, 3000r / min, etc., and the present invention is not limited thereto.

The present invention sets a variable frequency water pump in the drinking water device, determines the rotation speed signal according to the input signal, and then determines the speed regulation signal according to the rotation speed signal, so that the rotation speed of the variable frequency water pump can be adjusted according to demand. The drinking water device can adjust different water outlet flow rates through the variable frequency water pump, so that the drinking water device can meet multi-functional water intake needs, reduce the number of water pumps used, thereby reducing the manufacturing cost of the drinking water device, reducing the volume of the drinking water device, and simplifying the production process of the drinking water device.
