[0002] Smart toilets have entered thousands of households, facilitating people's daily use and providing a better user experience. In particular, zero-water-pressure toilets (i.e., toilets that can use a booster pump to draw water from the toilet tank for flushing) have effectively solved the problem of weak flushing force when the water pressure is insufficient. However, current smart toilets generally use traditional fixed-speed / linear methods to adjust the speed or power. The power conversion transition is not smooth, causing large changes in the water pressure and water speed of the water pump, resulting in large water flow noise and water hammer effect noise. In addition, due to the presence of air in the downflush pipe, the air and water flow collide easily during the flushing process, especially in the jet stage, to produce a gas explosion sound. The measured maximum flushing volume is mostly above 75dB, especially at night, the noise is obviously disturbing. Summary of the Invention

[0029] 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 drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments.

[0030] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0031] In one embodiment, Figure 1 This is a flow chart of a flushing control method for a smart toilet provided by an embodiment of the present invention. This embodiment is applicable to the case of noise reduction control during the flushing process of a smart toilet. The method can be executed by a flushing control device of a smart toilet. The flushing control device of the smart toilet can be implemented in the form of hardware and / or software. The flushing control device of the smart toilet can be configured in the smart toilet. Figure 1 As shown, the method includes:

[0032] S110 : In response to receiving a flushing instruction for the smart toilet, identifying and extracting a target valve opening and a power adjustment method for different flushing stages in the flushing instruction.

[0033] In one example, a flush command refers to a control signal or operating instruction that triggers a smart toilet to flush, either by the user or the system. In actual operation, a flush command can be sent to the smart toilet's control system or main controller via a specific input method (e.g., button, voice, or sensor), driving the motor and booster pump to complete the smart toilet's cleaning process. The flush command can be triggered in various ways, such as manually, automatically, by voice, or remotely. Among them, the flushing instruction is triggered manually, for example, a physical button (i.e., a flush button on the operation panel of the smart toilet or a remote control button), a knob or a touch screen (for example, the flushing function can be selected by rotating the button or touching the screen), gesture sensing (for example, near a specific sensing area of ​​the smart toilet or triggered by waving the hand) and other methods can be used to trigger the flushing instruction; the flushing instruction can be triggered automatically, for example, human body sensing (for example, it can be automatically triggered after the infrared sensor detects that the user has left the seat of the smart toilet), timed triggering (that is, preset periodic automatic flushing) or linkage triggering (that is, linkage with other devices, for example, after the smart bathroom mirror in the bathroom space detects that the user has left, the smart toilet is linked to flushing) and other methods to trigger the flushing instruction; the flushing instruction can be triggered by voice or remotely, for example, the flushing instruction can be remotely controlled by voice command (for example, through an intelligent voice assistant) or APP.

[0034] In one example, the target valve opening is used to characterize the degree of opening or position that the switching valve is expected to achieve according to the control requirements. Generally speaking, the valve opening is used to measure the parameters such as the flow rate, pressure or liquid level of the fluid regulated by the switching valve. In one example, the switching valve can be a rotary valve, and its valve opening can be characterized by the rotation angle. For example, the target valve opening has a value range of 10°-30°. In one example, the switching valve can also be a non-rotating valve, and its valve opening can be characterized by a percentage. For example, the target valve opening can have a value range of 0%-100%. For example, the target valve opening can be preferably set to 20°.

[0035] In one example, a power adjustment mode represents a method or strategy for adjusting or controlling the operating power of a booster pump in a smart toilet. The power adjustment mode may include at least one of the following: operating power changing over time in accordance with uniform acceleration, operating power changing over time in accordance with uniform deceleration, operating power remaining constant over time, or operating power changing over time in accordance with jerky acceleration.

[0036] In actual operation, the flushing process of a smart toilet includes: a brushing stage, a spraying stage, and a water replenishment stage. Different power adjustment methods are used in different flushing stages. For example, in the brushing stage, the power adjustment methods can include uniform acceleration, accelerated acceleration, uniform acceleration, and uniform deceleration; in the spraying stage, the power adjustment methods can include uniform acceleration, constant speed, and uniform deceleration; and in the water replenishment stage, the power adjustment methods can include uniform deceleration.

[0037] In one example, when the main controller of the smart toilet receives a flushing instruction for the smart toilet, it automatically identifies and extracts the target valve opening and the power adjustment methods corresponding to the three stages of brushing, spraying and water replenishment from the flushing instruction.

[0038] S120: Control the valve opening between the jet flow channel and the switching valve in the smart toilet according to the target valve opening.

[0039] In one example, the jet flow channel refers to the water pipe at the bottom of the smart toilet, that is, it corresponds to the water channel corresponding to the jet port in the smart toilet. In the initial stage of the smart toilet, the switching valve can be rotated to the jet flow channel to facilitate the subsequent flushing of the brush ring opening. Correspondingly, the valve opening between the jet flow channel and the switching valve is used to characterize the current valve opening of the switching valve of the jet flow channel. For example, assuming that the switching valve is a rotary valve and the target valve opening is 20°, the main controller can adjust the valve opening of the switching valve of the jet flow channel in the smart toilet to 20° to complete the dynamic adjustment process of the valve opening of the switching valve.

[0040] S130: Start the booster water pump in the smart toilet and automatically adjust the working power of the booster water pump in different flushing stages according to the power adjustment method.

[0041] Generally speaking, a booster water pump is configured at the water inlet of the smart toilet, and the booster water pump is connected to the water tank of the smart toilet. When the main controller receives a flushing command, the booster water pump can be started so that the booster water pump can pump water from the water tank and let the pumped water enter from the water inlet to complete the flushing process of the smart toilet.

[0042] In an embodiment, during the brushing stage, the power adjustment method may include four processes: uniform acceleration, accelerated acceleration, uniform acceleration and uniform deceleration. Correspondingly, the main controller may use these four processes to complete the adjustment of the working power of the booster water pump during the brushing stage, that is, it may control the steady adjustment of the working power of the booster water pump.

[0043] During the injection stage, the power adjustment method can include three processes: uniform acceleration, constant speed and uniform deceleration. Correspondingly, the main controller can use these three processes to complete the working adjustment of the booster water pump during the injection stage, that is, it can control the steady adjustment of the working power of the booster water pump.

[0044] During the water replenishment phase, the power adjustment method may include: uniform deceleration. Correspondingly, the main controller may use this process to complete the working adjustment of the booster water pump during the injection phase, that is, it may control the steady adjustment of the working power of the booster water pump.

[0045] It should be noted that, in order to ensure the continuity of the booster pump's operating power in different stages, the operating power is continuous between the brushing stage and the spraying stage, the operating power is continuous between the spraying stage and the water replenishing stage, and the operating power is continuous between the water replenishing stage and the brushing stage. Specifically, the operating power of the booster pump can be 0 at the beginning of the brushing stage, and similarly, the operating power of the booster pump can be 0 at the end of the water replenishing stage.

[0046] The technical solution of this embodiment, when receiving a flushing instruction for the smart toilet, identifies and extracts the target valve opening and the power adjustment method for different flushing stages from the flushing instruction, and controls the valve opening between the jet flow channel and the switching valve in the smart toilet according to the target valve opening, and then starts the booster water pump in the smart toilet, so that the water flow in the brushing stage can be used to exhaust the jet flow channel, which can solve the technical problem of high noise caused by the air explosion sound generated by the air and water flow in the downwash pipe in the subsequent jet stage; and, the power adjustment method for different flushing stages is used to automatically and dynamically adjust the working power of the booster water pump, thereby solving the technical problems of water flow impact sound caused by sudden acceleration changes in traditional constant speed or simple linear speed regulation in the prior art, and resonance noise between water flow and pipe, effectively reducing the flushing noise of the smart toilet, thereby improving the user experience.

[0047] In one embodiment, Figure 2 This is a flow chart of another smart toilet flushing control method provided by an embodiment of the present invention. This embodiment is based on the above embodiment and provides a detailed description of the valve opening adjustment process and the booster pump working power adjustment process. Figure 2 As shown, the method includes:

[0048] S210: In response to receiving a flushing instruction for the smart toilet, identifying and extracting a target valve opening and a power adjustment method for different flushing stages in the flushing instruction.

[0049] S220: Use the stepper motor in the smart toilet to adjust the valve opening between the jet flow channel and the switching valve in the smart toilet to the target valve opening.

[0050] In one example, a smart toilet incorporates a stepper motor connected to a switching valve, whose position is dynamically adjusted via the motor's rotating shaft. During the brushing phase, the switching valve is controlled to rotate to the jetting channel, closing the valve there. During the spraying phase, the switching valve is controlled to rotate to the secondary brushing port, closing the valve there. During the refilling phase, the switching valve is controlled to rotate to the jetting channel, closing the valve there.

[0051] During actual operation, the main controller of the smart toilet can control the rotation of the rotor in the stepper motor based on the target valve opening, so that the valve opening of the switching valve is adjusted to the target valve opening.

[0052] It should be noted that the stage of adjusting the valve opening of the switching valve of the injection flow channel to the target valve opening belongs to the brushing stage, that is, it is located in the initial position of the brushing stage, that is, the valve opening of the switching valve is first adjusted to the target valve opening through the main controller to complete the exhaust process of the injection flow channel, avoiding the gas explosion sound generated by the air and water flow in the downflow pipe and causing high noise, thereby effectively improving the user experience.

[0053] S230: Start the booster water pump in the smart toilet.

[0054] S240. When the smart toilet is in the flushing stage, the working power of the booster pump is dynamically adjusted in accordance with the power adjustment method of uniform acceleration, accelerated acceleration, uniform acceleration and uniform deceleration according to the working power changing with time.

[0055] In one embodiment, dynamically adjusting the working power of the booster pump according to the power adjustment methods of uniform acceleration, jerky acceleration, uniform acceleration, and uniform deceleration over time includes:

[0056] In the first time period, the working power of the booster water pump is adjusted according to a power adjustment method in which the working power changes with time in accordance with uniform acceleration;

[0057] In the second time period, the working power of the booster water pump is adjusted according to the power adjustment method in which the working power changes with time in accordance with the acceleration;

[0058] In the third time period, the working power of the booster water pump is adjusted according to a power adjustment method in which the working power changes with time in accordance with uniform acceleration;

[0059] In the fourth time period, the working power of the booster water pump is adjusted according to a power adjustment method in which the working power changes with time in accordance with uniform deceleration.

[0060] In one example, uniform acceleration can be understood as a process in which the power change rate is constant and positive, and uniform deceleration can be understood as a process in which the power change rate is constant and negative; and acceleration can be understood as a process in which the rate of change of the power change rate is constant and positive.

[0061] Assume that the uniform acceleration in the first time period corresponds to the first constant power change rate, the acceleration in the second time period corresponds to the rate of change of the constant power change rate, the uniform acceleration in the third time period corresponds to the second constant power change rate, and the uniform deceleration in the fourth time period corresponds to the third constant power change rate, and the first constant power change rate, the second constant power change rate, and the third constant power change rate are respectively recorded as constant power change rate 1, constant power change rate 2, and constant power change rate 3. In the circling stage, the power change rate process is: constant power change rate 1, the rate of change of the constant power change rate, constant power change rate 2, and constant power change rate 3, among which constant power change rate 1 and constant power change rate 2 are positive values, that is, the process of linear power increase; the rate of change of the constant power change rate is positive, that is, the rate of change of the power change rate is constant; constant power change rate 3 is negative, that is, the process of linear power decrease. It can be understood that, in the initial stage of the brushing stage, the working power of the booster water pump increases linearly according to the constant power change rate 1; then it accelerates and speeds up according to the change rate of the constant power change rate; then it increases linearly again according to the constant power change rate 2; and finally it decreases linearly according to the constant power change rate 3, thus completing the steady increase and decrease process of the working power of the booster water pump in the brushing stage. It can also be understood that the working power of the booster water pump continues to increase according to uniform acceleration in the first time period, continues to increase according to accelerated acceleration in the second time period, continues to increase according to uniform acceleration in the third time period, and continues to decrease according to uniform deceleration in the fourth time period.

[0062] It should be noted that the constant power change rate 1 and the constant power change rate 2 may be different, which can also be understood as that the power change rates in the first time period and the third time period are different.

[0063] S250. When the smart toilet is in the spraying stage, the working power of the booster pump is dynamically adjusted in accordance with the power adjustment methods of uniform acceleration, constant speed and uniform deceleration according to the working power changing with time.

[0064] In one embodiment, dynamically adjusting the working power of the booster pump according to the power adjustment methods of uniform acceleration, constant speed, and uniform deceleration in sequence according to the working power changing over time includes:

[0065] In the fifth time period, the working power of the booster water pump is adjusted according to the power adjustment method in which the working power changes with time in accordance with uniform acceleration;

[0066] In the sixth time period, the working power of the booster water pump is adjusted according to a power adjustment method in which the working power changes with time in accordance with a constant speed;

[0067] In the seventh time period, the working power of the booster water pump is adjusted according to the power adjustment method that the working power changes with time and conforms to uniform deceleration.

[0068] In one example, constant speed can be understood as the process where the booster pump's operating power is constant; uniform acceleration can be understood as a process where the power rate of change is constant and positive; and uniform deceleration can be understood as a process where the power rate of change is constant and negative. Assume that the uniform acceleration in the fifth time period corresponds to the fourth constant power rate of change, and the uniform deceleration in the seventh time period corresponds to the fifth constant power rate of change. The fourth and fifth constant power rates of change are denoted as constant power rate of change 4 and constant power rate of change 5, respectively. During the injection phase, the power rate of change progresses sequentially: constant power rate of change 4, constant power, and constant power rate of change 5. Constant power rate of change 4 is positive, indicating a linear increase in power; constant power rate of change 5 is negative, indicating a linear decrease in power. This means that, at the beginning of the injection phase, the booster pump's operating power increases linearly at constant power rate of change 4; then operates at constant power; and finally, linearly decreases at constant power rate of change 5, completing the steady increase and decrease of the booster pump's operating power during the injection phase. It can also be understood that the working power of the booster pump continues to increase according to uniform acceleration in the fifth time period, maintains the working power unchanged according to a constant speed in the sixth time period, and continues to decrease according to uniform deceleration in the seventh time period.

[0069] S260. When the smart toilet is in the water replenishment stage, the working power of the booster pump is dynamically adjusted according to the power adjustment method of uniform deceleration according to the working power changing with time until the booster pump is turned off.

[0070] In one embodiment, the working power of the booster water pump is dynamically adjusted according to a power adjustment method that conforms to uniform deceleration in accordance with the working power changing over time, including: adjusting the working power of the booster water pump according to a power adjustment method that conforms to uniform deceleration in a ninth time period.

[0071] In one example, the uniform deceleration process can be understood as a process in which the power change rate is constant and negative. Assume that the ninth time period corresponds to the sixth constant power change rate, and the sixth constant power change rate is recorded as constant power change rate 6. During the water replenishment stage, the power change rate process includes: a constant power change rate 6, wherein the constant power change rate 6 is a negative value, that is, a process in which the power decreases linearly. It can be understood that during the water replenishment stage, the working power of the booster water pump decreases linearly according to the constant power change rate 6, thereby completing the process in which the working power of the booster water pump decreases steadily during the water replenishment stage.

[0072] It should be noted that before entering the ninth time period, the operating power of the booster pump needs to be increased during the eighth time period to quickly increase the water flow rate to the replenishment water flow rate. In this embodiment, the operating power of the booster pump can be increased during the eighth time period by adjusting the operating power to achieve uniform acceleration over time. The eighth time period is between the seventh and ninth time periods.

[0073] The technical solution of this embodiment, based on the above embodiment, is to complete the exhaust process of the jet flow channel by adjusting the valve opening between the jet flow channel and the switching valve to the target valve opening at the initial stage of the brushing stage, and to discharge the air in the jet flow channel and the switching valve out of the jet outlet. This solves the technical problem of high noise caused by the explosion sound generated by the air and water flow in the downwash pipe during the subsequent spraying stage, and effectively reduces the flushing noise. In addition, different constant power change rates and change rates of the constant power change rate are used to steadily increase and decrease the working power of the booster water pump during the brushing stage, and different constant power change rates and constant power are used to steadily adjust the working power of the booster water pump during the spraying stage. Finally, a constant power change rate is used to steadily decrease the working power of the booster water pump during the water replenishment stage until the booster water pump is shut down. This effectively achieves steady adjustment of the working power of the booster water pump during different flushing stages, effectively overcomes the problems of water flow collision sound caused by sudden acceleration changes and resonance noise between water flow and pipes in traditional constant speed / simple linear speed regulation, and effectively improves the user experience.

[0074] In one embodiment, after controlling the valve opening between the jet flow channel and the switching valve in the smart toilet according to the target valve opening, it also includes: when the duration of the valve opening between the jet flow channel and the switching valve being adjusted to the target valve opening reaches a first preset duration, the switching valve of the jet flow channel is switched to a fully closed state.

[0075] In one example, the first preset time is used to characterize the exhaust time of the jet flow channel in the smart toilet. In one example, the value range of the first preset time can be 1 to 2 seconds. Exemplarily, preferably, the first preset time can be 1 second (s). When the valve opening between the jet flow channel and the switching valve is adjusted to the target valve opening, the timing starts, and when the valve opening of the switching valve is maintained at the target valve opening for a duration reaching the first preset time, the main controller completely closes the switching valve of the jet flow channel so that the water flowing in from the water inlet can flow out completely from the brush ring port to avoid water diversion from the jet flow channel.

[0076] In one embodiment, before controlling the valve opening between the jet flow channel and the switching valve in the smart toilet according to the target valve opening, the flushing control method of the smart toilet also includes: controlling the switching valve of the jet flow channel in the smart toilet to switch to a fully closed state.

[0077] In one example, before controlling the valve opening between the jet flow channel and the switching valve in the smart toilet according to the target valve opening, the main controller can switch the switching valve of the jet flow channel in the smart toilet to a fully closed state to complete the resetting process of the switching valve, and then adjust the valve opening of the switching valve, which can effectively ensure the accuracy of subsequently switching the valve opening of the switching valve to the target valve opening.

[0078] In one embodiment, within the second preset time period between switching from the brush ring stage to the spray stage, the flushing control method of the smart toilet also includes: using a stepper motor in the smart toilet to switch the switching valve from the spray flow channel to the brush ring port, and closing the brush ring flow channel corresponding to the brush ring port.

[0079] In one example, the second preset duration is used to characterize the last period of time that the booster pump is in the brushing stage. For example, the second preset duration can be 0.5s. Within the second preset duration before the booster pump switches from the brushing stage to the spraying stage, the stepper motor in the smart toilet is used to switch the switching valve from the jet flow channel to the brushing port, and close the brushing flow channel corresponding to the brushing port. This can effectively avoid full power to the brushing port, thereby avoiding the water hammer effect caused by a small amount of air in the pipe and too rapid water flow, resulting in relatively loud noise. In addition, the stepper motor in the smart toilet can swing, and there is water in the space where the switching valve and stepper motor of the smart toilet are located. If the water flow is too rapid, resulting in resistance to the swing of the stepper motor, the switching valve can be switched within the second preset duration to reduce the power of the booster pump and avoid excessive swing resistance.

[0080] In one embodiment, within the third preset time period between switching from the spraying stage to the water replenishing stage, the flushing control method of the smart toilet also includes: using a stepper motor in the smart toilet to switch the switching valve from the brush ring port to the jet flow channel, and closing the jet flow channel.

[0081] In one example, the third preset time is used to characterize the last period of time that the booster water pump is in the spraying stage. For example, the third preset time can be 0.5s. During the third preset time between the booster water pump switching from the spraying stage to the water replenishment stage, the stepper motor in the smart toilet is used to switch the switching valve from the brush ring port to the jet flow channel and close the jet flow channel. This can effectively avoid full power to the jet flow channel, thereby avoiding the water hammer effect caused by the small amount of air in the pipe and the rapid water flow, which leads to relatively loud noise. In addition, the stepper motor in the smart toilet can swing, and there is water in the space where the switching valve and stepper motor of the smart toilet are located. If the water flow is too rapid, resulting in resistance to the swing of the stepper motor, the switching valve can be switched within the third preset time to reduce the power of the booster water pump and avoid excessive swing resistance.

[0082] In one embodiment, Figure 3 This is a flow chart of another method for controlling flushing of an intelligent toilet provided by an embodiment of the present invention. This embodiment, as a preferred embodiment, illustrates the flushing control process of the intelligent toilet. In this embodiment, the first time period, the second time period, the third time period, the fourth time period, the fifth time period, the sixth time period, the seventh time period, the eighth time period, and the ninth time period are respectively denoted as t1, t2, t3, t4, t5, t6, t7, t8, and t9. For example, the total duration of the flushing phase (i.e., the time periods t1, t2, t3, and t4) can be 4.8 seconds, the total duration of the spraying phase (i.e., the time periods t5, t6, and t7) can be 5 seconds, and the total duration of the water replenishment phase (i.e., the time period t9) can be 6.8 seconds.

[0083] The flushing process in this embodiment includes the following three stages: a brushing (exhaust) stage, a spraying stage, and a water replenishment stage. The power change rate processes in the brushing stage are: constant power change rate 1 (i.e., uniform acceleration stage), constant power change rate (i.e., acceleration stage), constant power change rate 2 (i.e., uniform acceleration stage), and constant power change rate 3 (i.e., uniform deceleration stage), and the corresponding durations are: t1-t4. The power change rate processes in the spraying stage are: constant power change rate 4 (i.e., uniform acceleration stage), constant power (i.e., constant speed stage), and constant power change rate 5 (i.e., uniform deceleration stage), and the corresponding durations are: t5, t6, and t7. In the water replenishment stage, the power change rate processes include: constant power change rate 6 (i.e., uniform deceleration stage), and the corresponding duration is t9. Furthermore, the first preset duration is 1s, the second preset duration and the third preset duration are both 0.5s, and the target valve opening is 20°.

[0084] It should be noted that before entering the time period t9, the operating power of the booster pump needs to be increased in the time period t8 to quickly increase the water speed to the water replenishment speed. For example, the operating power of the booster pump in the time period t8 can be increased by using a power adjustment method that satisfies uniform acceleration over time.

[0085] like Figure 3 As shown, the flushing control of the smart toilet in this embodiment includes the following steps:

[0086] Step 1: Determine whether a flushing instruction is received. If so, proceed to step 2.

[0087] Step 2: Control the switching valve of the injection channel to close, and then switch the valve opening of the switching valve to 20°.

[0088] Step 3: Start the booster water pump.

[0089] Step 4: perform the circle brushing process during the t1-t4 phase.

[0090] Step 5, determine whether the exhaust process is completed in the ring brushing stage, if so, execute step 6; if not, return to step 4.

[0091] Step 6: Control the switching valve and the injection channel to close.

[0092] Step 7: Check whether the total duration of t1+t2+t3+t4 is obtained. If so, execute step 8; if not, execute step 5.

[0093] Step 8: The switching valve is switched to the position of the brush ring opening, and the brush ring flow channel corresponding to the brush ring opening is closed.

[0094] Step 9: perform the injection process during the t5-t7 period.

[0095] Step 10: Check whether the total duration of t5+t6+t7 is obtained. If so, execute step 11; if not, execute step 9.

[0096] Step 11: The switching valve is switched to the position of the injection flow channel, and the injection flow channel is closed.

[0097] Step 12: Perform water replenishment at stage t9. Step 13: Check whether flushing is complete. If yes, then the process ends; if not, then return to step 12.

[0098] In one example, Figure 4 This is a structural schematic diagram of a valve in an exhaust state provided by an embodiment of the present invention; Figure 5 This is a structural diagram of a valve provided by an embodiment of the present invention in the brushing or water replenishing stage; Figure 6 This is a structural diagram of a valve in the injection stage provided by an embodiment of the present invention; Figure 7 This is a schematic diagram of a curve between the working power and time of a booster water pump provided by an embodiment of the present invention.

[0099] like Figure 7 As shown in FIG, during the brushing stage, i.e., t1-t4, the control process of the booster water pump can be divided into four stages: uniform acceleration stage, accelerated acceleration stage, uniform acceleration stage, and uniform deceleration stage. 0.5S before the end of the deceleration stage t4, the valve of the switching valve is switched to the brushing port and the brushing port is closed, as shown in FIG. Figure 5 shown.

[0100] In particular, after receiving the flushing instruction and before the start of the brushing stage, the angle between the switching valve and the injection flow channel corresponding to the injection port is controlled to be 20 degrees, such as Figure 4 As shown, the water flow in the brushing stage is used for pre-exhaust for 1S, and then the switching valve of the injection flow channel is closed.

[0101] In the injection stage: i.e. t5-t7, the control process of the booster pump is divided into three stages: uniform acceleration stage, constant speed stage and uniform deceleration stage; 0.5S before the end of the uniform deceleration stage t7, the valve of the switching valve is switched to the injection flow channel and the injection flow channel is closed. Figure 6 shown.

[0102] During the water replenishment phase: i.e. t9, the booster pump decelerates evenly and slowly until the pump shuts down.

[0103] It should be noted that if Figure 7As shown, before entering the time period t9, the working power of the booster pump needs to be increased in the time period t8 to quickly increase the water speed to the water replenishment speed. For example, the working power of the booster pump can be increased in the time period t8 by using a power adjustment method that satisfies uniform acceleration with time.

[0104] The driving power at the connection point of the speed in the above three stages is continuous, and the speed increases slowly. This control method can overcome the water flow impact sound caused by the sudden acceleration change in traditional constant speed / simple linear speed regulation, as well as the resonance noise between the water flow and the pipeline, to the greatest extent, effectively improving the user experience.
