[0033] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of the present invention and are not intended to limit the present invention.

[0035] To better understand the technical solution of the present invention, a detailed description will be provided below in conjunction with the accompanying drawings and specific embodiments.

[0036] The execution subject of the control method embodiment of the variable frequency water purification system of the present invention can be a computing service device with data processing, network communication and program execution functions, such as a control device for a water purification system, a water purifier, or an electronic device or control device capable of realizing the above functions. The following uses a water purifier as an example to describe the following embodiments.

[0037] Due to the urgent need for healthy drinking water, water purifiers and similar products have become indispensable household appliances. Variable frequency water systems, with their core component being a variable frequency pump, are gradually becoming the future trend in water purifier development due to their energy-saving advantages and intelligent adjustment under different operating conditions. When a user draws water, the water purifier enters water production mode, and the user experiences the noise at close range. During filter self-cleaning maintenance, the water purifier enters flushing mode, and the user experiences flushing noise unexpectedly, often leading to a poor noise experience. Both water production and flushing noises are more abrupt and disturbing at night in relatively quiet environments. Flushing noise, in particular, has a certain degree of randomness, and because users are not prepared for it, it results in more noise complaints.

[0038] Considering that variable frequency water purifiers have core components such as variable frequency pumps, this invention provides a feasible way to effectively improve the noise experience during nighttime use or filter maintenance. The technical solution of this invention is based on a variable frequency pump to implement a control method for a variable frequency water purification system, which adaptively reduces water production noise and flushing noise according to the current time period, thereby improving the user experience.

[0039] To overcome the technical defects existing in the prior art, embodiments of the present invention provide a control method for a variable frequency water purification system, referring to... Figure 1 , Figure 1 This is a flowchart illustrating an embodiment of the control method for the variable frequency water purification system of the present invention. In Embodiment 1, the control method for the variable frequency water purification system includes:

[0040] Step S10: When in silent mode, adjust the speed of the variable frequency pump in the variable frequency water purification system in water production mode to the first speed.

[0041] Step S20: When in non-silent mode, adjust the speed of the variable frequency pump in water production mode to a second speed, wherein the second speed is greater than the first speed.

[0042] Steps S10 and S20 are parallel and are used to represent the variable frequency pump speed control strategies under different conditions.

[0043] In addition, the noise emitted by the variable frequency water purification system in the silent mode is lower than that in the non-silent mode.

[0044] For example, the silent mode and the non-silent mode can be determined by a preset time period or user control command. For instance, the silent mode and non-silent mode can correspond to time periods preset by the user. The silent time period can be the time when the user needs to rest, such as 11:00 PM to 6:00 AM, while the non-silent time period is other time periods, such as 6:00 AM to 11:00 PM. Users can also set other silent time periods according to actual needs. For example, if there is a need for a midday rest, a silent time period from 12:00 PM to 2:00 PM can be added, thereby minimizing noise during the water purifier's water production process. In this case, the machine's time needs to be calibrated and updated first, as accurate machine time is the basis for time-segmented control. The machine's time can be calibrated according to a preset frequency to ensure consistency with the standard time, and then the current time period can be determined. Taking a water purifier as an example, after completing the calibration and update, it is determined whether the current time point is in silent mode or non-silent mode. In addition, users can manually send control commands to switch the variable frequency water purification system to silent mode or non-silent mode to meet noise reduction needs in other scenarios.

[0045] In this embodiment of the invention, noise is primarily reduced by controlling the speed of the variable frequency pump. During the water purification process, the variable frequency pump operates to filter the raw water to obtain pure water, which generates considerable noise. Reducing the speed of the variable frequency pump in this embodiment, while decreasing the flow rate of pure water, also reduces noise. During user rest periods, appropriately lowering the initial speed to control the pump improves the user's water intake experience. Furthermore, in non-silent mode, the normal water purification speed can be used to maintain a certain flow rate of pure water.

[0046] For example, the first speed is the silent mode, which can be 1100 rpm, and the second speed is the normal mode, which can be 1300 rpm.

[0047] This invention provides a control method for a variable frequency water purification system. The method mainly controls the variable frequency pump to operate at different speeds during water production in silent and non-silent modes. Specifically, it operates at a lower speed in silent mode, thereby reducing the water production noise in silent mode, avoiding the impact of loud noise on users when taking water, reducing noise interference to other people in the indoor environment, and improving the user experience.

[0048] In one feasible embodiment, the control method for the variable frequency water purification system further includes:

[0049] Step S30: When in the silent mode, adjust the wastewater valve in the water production mode of the variable frequency water purification system to the first position.

[0050] Step S40: When in the non-silent mode, adjust the wastewater valve in the water production mode to the second position, wherein the flow rate of the second position is greater than the flow rate of the first position.

[0051] It should be noted that steps S30 and S40 are parallel steps, which are control steps for the wastewater valve at different times. In addition, steps S10 and S20 are parallel steps to steps S30 and S40. Specifically, when in silent mode, steps S10 and S30 are executed, and when in non-silent mode, steps S20 and S40 are executed.

[0052] The variable frequency water system of the water purifier in this embodiment of the invention includes core components such as a variable frequency pump and an intelligent wastewater valve. The variable frequency pump can quickly adjust its speed according to actual scenarios or conditions. The intelligent wastewater valve can adjust the wastewater flow rate according to actual scenarios or conditions.

[0053] To prevent an excessive decrease in pure water flow rate, the wastewater valve is adjusted to a relatively low first setting while the frequency converter pump speed is reduced. This is understandable because if the wastewater valve flow rate remained unchanged while the frequency converter pump speed was reduced, the decrease in inlet water volume would lead to a decrease in pure water volume, affecting the user's water intake efficiency. Therefore, it is necessary to simultaneously reduce the wastewater valve flow rate to direct more water to the pure water outlet and maintain the pure water flow rate. Additionally, in non-silent mode, the frequency converter pump operates at a higher speed, allowing the wastewater valve to remain at a relatively high second setting. Assuming no noticeable difference in user visual experience, a slight decrease in pure water flow rate is permissible, with a maximum reduction of 300ml.

[0054] For example, the first flow rate can be 800cc, and the second flow rate can be 1000cc.

[0055] In the technical solution of this invention, the wastewater valve is adaptively adjusted at different times, and this adjustment is coordinated with the frequency converter pump. This ensures that the pure water flow rate does not decrease excessively when the frequency converter pump slows down, thus maintaining the pure water output efficiency and improving the user's experience with the water purifier.

[0056] In another feasible embodiment, the control method of the variable frequency water purification system further includes:

[0057] Step A10: When in the silent mode, control the variable frequency pump in the flushing mode of the variable frequency water purification system to stop running, and adjust the wastewater valve to the third position, wherein the flow rate of the third position is greater than the flow rate of the second position.

[0058] Additionally, it should be noted that the variable frequency water purification system also has a filter cleaning function, which mainly cleans the filter by rinsing it with a strong water flow. Compared to the water production mode, the variable frequency water purification system produces more noise during the flushing mode. Furthermore, because the flushing mode is somewhat random and unpredictable for users, the noise impact is greater than that of the water production mode.

[0059] To reduce noise in silent mode during flushing, the variable frequency pump can be stopped during flushing, allowing the variable frequency water purification system to complete filter cleaning and self-maintenance under natural water pressure, achieving low-noise flushing in silent mode. Additionally, in this embodiment, the wastewater valve is adjusted to a third setting, higher than the second setting, to accelerate wastewater flow.

[0060] Correspondingly, in one feasible embodiment, the control method of the variable frequency water purification system further includes:

[0061] Step A20: When in the non-silent mode, adjust the variable frequency pump in the flushing mode of the variable frequency water purification system to the first speed and adjust the wastewater valve to the third position.

[0062] In non-silent mode, to maintain a high level of flushing effect for the variable frequency water purification system, the wastewater valve is adjusted to the third position to accelerate wastewater flow. The variable frequency pump speed is set to the first speed. The reason for setting the variable frequency pump to a higher second speed is to take into account that the start time of the flushing mode is uncertain, and users have no psychological expectation of it. Appropriately reducing the speed of the variable frequency pump can reduce the impact of noise on users, thereby solving the negative experience caused by the flushing noise of the water purifier.

[0063] For example, when the wastewater valve is in the third position, the wastewater valve is fully open, so that all the wastewater generated during the rinsing process flows out as quickly as possible, improving the cleaning and self-maintenance efficiency of the filter element.

[0064] Based on the foregoing embodiments, when the silent mode and non-silent mode correspond to time periods, the correspondence between the water purifier's mode, time period, variable frequency pump speed, and wastewater valve setting in this embodiment of the invention is as follows: Figure 2 As shown, when the water purifier is in water production mode, the variable frequency pump speed and wastewater valve setting are both at the first speed and the second speed respectively during the quiet period. When the water purifier is in flushing mode, the variable frequency pump speed is 0 and the wastewater valve setting is at the third speed respectively during the quiet period. When the water purifier is in flushing mode, the variable frequency pump speed is 0 and the wastewater valve setting is at the third speed respectively during the quiet period.

[0065] It should be noted that, in the above methods for adjusting the speed and gear of the variable frequency pump and wastewater valve, the first speed of the variable frequency pump and the first gear of the wastewater valve corresponding to the silent mode were obtained by testing the variable frequency water purifier and user noise experience; the second speed of the variable frequency pump and the second and third gears of the wastewater valve corresponding to the non-silent mode are the default settings of the water purifier at the factory.

[0066] For example, when the silent mode is from 23:00 to 06:00 and the non-silent mode is from 06:00 to 23:00, the variable frequency pump speed and wastewater valve position in various modes during different time periods are shown in Table 1 below.

[0067]

[0068] Table 1

[0069] In another feasible embodiment, if the silent mode includes two time periods (23:00-06:00 and 12:00-14:00), the variable frequency pump speed and wastewater valve position are shown in Table 2 below.

[0070]

[0071] Table 2

[0072] The table above can be used to control the variable frequency pump and wastewater valve of the variable frequency water purification system in silent mode and non-silent mode. Moreover, it can be updated online via OTA (Over-the-Air Technology) through the application or enterprise backend bound to the variable frequency water purification system, so as to meet the user's needs for adjusting the silent mode according to the actual situation.

[0073] For ease of understanding, in conjunction with the foregoing embodiments of the invention, and referring to... Figure 3A feasible control method for a variable frequency water purification system may include the following steps: first, performing machine time calibration, then performing machine time detection to determine whether the current time point is within a preset silent period. If so, the silent period strategy is activated, adjusting the variable frequency pump to the first speed and the wastewater valve to the first position in water production mode, and turning off the variable frequency pump and adjusting the wastewater valve to the third position in flushing mode. If not, the non-silent period strategy is activated, adjusting the variable frequency pump to the second speed and the wastewater valve to the second position in water production mode, and adjusting the variable frequency pump to the first speed and the wastewater valve to the third position in flushing mode.

[0074] This invention also provides a variable frequency water purification system, wherein the variable frequency water purification system includes:

[0075] A variable frequency pump, used to control the water flow pressure in the variable frequency water purification system;

[0076] The control unit is configured to adjust the speed of the variable frequency pump in water production mode to a first speed when in silent mode, and to adjust the speed of the variable frequency pump in water production mode to a second speed when in non-silent mode, wherein the second speed is greater than the first speed.

[0077] The variable frequency water purification system in this embodiment of the invention can be applied to water purifiers. This system includes a variable frequency pump whose speed can be controlled and changed according to actual conditions. A higher speed results in higher water pressure and flow rate; a lower speed results in lower water pressure and flow rate. Furthermore, the system also includes a control unit with timing and storage functions. This control unit can read the current time point and compare it with a preset quiet period to determine whether the current period is quiet or not. Based on the current time period, it executes different control strategies, sending control commands to the variable frequency pump to operate at a pre-stored first or second speed, thereby reducing noise generated during water purification.

[0078] In one embodiment, the variable frequency water purification system further includes a wastewater valve, which is used to control the flow rate of wastewater in the variable frequency water purification system;

[0079] The control unit is also configured to adjust the wastewater valve in the water production mode to a first position when in the silent mode, and to adjust the wastewater valve in the water production mode to a second position when in the non-silent mode, wherein the flow rate of the second position is greater than that of the first position.

[0080] The wastewater valve is an intelligent wastewater valve that can adjust its outlet flow rate according to control commands issued by the control unit. The higher the valve's setting, the greater the wastewater flow rate. Furthermore, the control unit can send control commands in silent mode to adjust the wastewater valve to the first setting, and in non-silent mode to adjust it to the second setting. This ensures that the wastewater flow rate matches the variable frequency pump's speed, preventing a significant reduction in pure water flow rate in silent mode.

[0081] It should also be noted that the control unit can also be used to perform other steps of the control method of the variable frequency water purification system in the above embodiment, including adjusting the speed of the variable frequency pump and the position of the wastewater valve in the flushing mode to reduce the adverse effects of noise caused by the flushing mode on the user.

[0082] For ease of understanding, by way of example, refer to Figure 4 The variable frequency water purification system may also include components such as a high-pressure switch, outlet valve, flow meter, water dispenser, check valve 1, check valve 2, reflux valve, inlet valve, inlet water TDS (Total Dissolved Solids), pure water TDS, variable frequency pump, intelligent wastewater valve, wastewater outlet, pre- and post-filters, and reverse osmosis filter. Figure 4 The connection is as shown. The high-pressure switch controls the start, operation, and stop of the water purifier, and monitors pressure fluctuations during operation. In case of any abnormality, it immediately cuts off the power to ensure the safe and reliable operation of the water purifier. The outlet valve controls the flow rate of the pure water outlet, and the flow meter detects the flow rate. The water dispenser can provide heating and cooling for the water. One-way valves 1-2, the inlet valve, and the return valve all control the flow rate of tap water. The inlet TDS and pure water TDS are used to detect the water quality of the inlet and pure water. The pre- and post-filters and the reverse osmosis filter are used to filter tap water, and the wastewater outlet discharges wastewater.
