Example two

Referring to fig. 9, the present embodiment provides a flushing control method applied to a water purifying apparatus, especially a water purifying apparatus having an integrated valve, and referring to fig. 1, the flushing control method includes the following steps:

and S11, acquiring the pollution and blockage parameters.

Use water purification unit as an example, because there is impurity in the aquatic, the filter core can have the jam to a certain extent after long-term the use, dirty stifled parameter is used for the jam state of sign filter core, when the filter core blockked up the certain degree, need wash the filter core to guarantee the normal filter effect of filter core. The fouling parameters may include: current influent flow rate or current influent pressure. The current water inflow rate can be acquired through a flow rate detection device, preferably, the flow rate detection device can be a flowmeter or a flow sensor; a flow meter or flow sensor may be provided on the water inlet line. The current pressure of intaking can acquire, preferably through pressure measurement device, pressure measurement device can be manometer or pressure sensor, and manometer or pressure sensor can set up on the inlet line.

And S12, judging whether the pollution and blockage parameter reaches a pollution and blockage threshold value.

The fouling threshold may be a preset value used to indicate that the filter element has become clogged to a critical value that requires flushing. Taking the water purifying apparatus as an example, when the dirt blocking parameter is the current inflow flow value, the dirt blocking threshold may be set to the maximum flow value (e.g., 4.3l/min) flowing through the inflow pipeline when the flushing is required, and the person skilled in the art may also determine the dirt blocking parameter according to actual needs. When the dirt blocking parameter is the current water inlet pressure value, the dirt blocking threshold value can be set to the maximum pressure value of the water inlet pipeline flowing through when the flushing is needed, and the dirt blocking parameter can be determined by a person skilled in the art according to actual needs. And after the pollution blocking parameter is obtained, comparing the pollution blocking parameter with a pollution blocking threshold value, and determining the relation between the pollution blocking parameter and the pollution blocking threshold value.

And S13, when the dirt blocking parameter reaches a dirt blocking threshold value, controlling the integrated valve to act according to a preset flushing strategy.

When the dirt blocking parameter reaches a dirt blocking threshold value, it can be determined that the filter element is blocked to a state needing to be washed, and a washing strategy needs to be executed to ensure normal use of the filter element in a subsequent stage. Specifically, when the dirt blocking parameter reaches the dirt blocking threshold, the filter element can be flushed according to a preset flushing strategy by controlling the action of the integrated valve.

According to the flushing control method provided by the embodiment, the dirty blocking parameter is obtained, whether the dirty blocking parameter reaches the dirty blocking threshold value or not is judged, and after the dirty blocking parameter reaches the dirty blocking threshold value, the integrated valve is controlled to act according to the preset flushing strategy, so that the execution of the flushing strategy is determined according to the actual blocking condition of the filter element, the timeliness of the execution of the flushing strategy is ensured, the condition that the filter element is flushed in advance or cleaned after being delayed is avoided, the accuracy of the execution of the flushing strategy is improved, and the water-saving effect is achieved on the basis of the requirement on the maximum service life of the filter element.

Specifically, when the dirty stifled parameter reaches dirty stifled threshold value, before control integrated valve carries out the action according to presetting the washing tactics, still include:

acquiring a filter element form, and determining a flushing mode based on the filter element form;

when the filter element is a single independent filter element, the flushing mode is determined to be intermittent flushing;

when the filter element is a filter element or a plurality of independent filter elements, the flushing mode is determined to be alternative flushing.

In this embodiment, the filter element may be a single independent filter element, or a plurality of independent filter elements.

When the single independent filter element is adopted, the filter element is only provided with one water inlet and one water outlet, raw water enters from the water inlet and flows out from the water outlet in the water preparation stage, and raw water or purified water enters from the water outlet and flows out from the water inlet in the flushing stage, so that the back flushing of the single independent filter element is realized; at the moment, the single independent filter element is washed intermittently only by controlling the opening and closing of the valve.

When the filter elements are adopted, at least two filter elements are arranged in parallel in one filter element, for simplifying the description, the case that two filter elements are arranged in parallel in one filter element is taken as an example for explanation, and because the two filter elements are both provided with a water inlet and a water outlet, raw water can respectively enter from the water inlets of the two filter elements and respectively discharge from the water outlets of the two filter elements in a water preparation stage; in the flushing stage, raw water can enter from the water inlet of the first filter element, the raw water is discharged from the water outlet of the first filter element after being filtered by the first filter element, purified water discharged from the water outlet of the first filter element enters the inside of the second filter element through the water outlet of the second filter element, and the second filter element is backwashed outwards by the inside of the second filter element, so that the flushed sewage is discharged from the water inlet of the second filter element, and the effect of flushing the second filter element by means of the purified water prepared by the first filter element is realized. On the contrary, the effect of washing the first filter element by the purified water prepared by the second filter element can be realized, and the specific process is not repeated herein. Therefore, when the filter element is in the form of a filter element, a flushing mode of alternate flushing can be adopted.

When the filter core is many independent filter cores, the water route flow direction of its inside is the same with when adopting the filter core, and no longer repeated here. Therefore, when the filter core is filter core or many independent filter cores, can confirm that the mode of washing is for washing in turn to borrow by the water purification improvement washing effect that makes, guarantee to wash clean degree.

Specifically, when the filter element is a filter element or a plurality of independent filter elements, after the flushing mode is determined to be the alternate flushing, the method includes: determining the flushing time T based on the dirt blocking parameter and the corresponding relation between the dirt blocking parameter and the flushing time_{General assembly}。

Time of flushing T_{General assembly}The determination of the flow rate needs to be determined based on the acquired dirt blocking parameter and the corresponding relation between the dirt blocking parameter and the flushing time, the corresponding relation between the dirt blocking parameter and the flushing time can be measured before delivery, a flow sensor is installed on a waterway, the flow rate pulse number under different water inlet pressures is recorded through experimental tests, and the water inlet pressure and the flow meter pulse number are stored through a controller. When water inlet pressure needs to be detected, the detected flow pulse number is transmitted to the controller, and the controller matches the detection value with the recorded value to find out corresponding water inlet pressure.

Different pressure P of intaking corresponds different washing time T, and pressure is big more, and washing time is short more. When the water inlet pressure is detected to be P1, the corresponding filter element flushing time is matched to be T1 through a program; when the water inlet pressure is detected to be P2, the corresponding filter element flushing time is matched to be T2 through a program; when the water inlet pressure is detected to be P3, the corresponding filter element flushing time is matched to be T3 through the program.

Further, in order to improve the detection accuracy of the water inlet pressure, the recorded data are detected for multiple times in the morning, at noon and evening, when the detection values are within the set range value, the controller matches the detection values with the recorded values, and the water inlet pressure value is determined.

Specifically, when the dirty stifled parameter reaches dirty stifled threshold value, control the integrated valve and carry out the action according to presetting the strategy of washing, include:

adjusting the integrated valve to a first flushing state for a retention time T_{General assembly}/2n；

Adjusting the integrated valve to a second flushing state for a retention time T_{General assembly}/2n；

Repeating the cycle of the first flushing state and the second flushing state for a total of n times;

and adjusting the action of the integrated valve to an initial state.

In this embodiment, the integrated valve is provided with a motor, and the motor drives the valve core to rotate, thereby adjusting the open-close state of the integrated valve. For example, in the initial state, the angle of the motor shaft is 0 °, and at this time, raw water enters from the water inlets of the two filter elements and is discharged from the water outlets of the two filter elements. When the dirt blocking parameter is determined to reach the dirt blocking threshold value, the integrated valve acts to a first flushing state, for example, a signal is received by the controller, the controller transmits the signal to the motor, the motor shaft is controlled to rotate from 0 degrees to a first angle value (for example, +5 degrees), and at the moment, raw water can enter from the water inlet of the first filter element, so that the raw water can enter the first filter elementThe sewage after flushing is discharged from the water inlet of the second filter element, thereby realizing the effect of flushing the second filter element by the clean water prepared by the first filter element, and the retention time T is in the state_{General assembly}2n (e.g., 30 seconds). After the first flushing state is maintained for a certain time, the integrated valve is moved to a second flushing state, for example, the motor shaft is rotated from a first angle value (e.g., +5 °) to a second angle value (e.g., -5 °), at this time, raw water can be introduced from the water inlet of the second filter element, and the flushed sewage is discharged from the water inlet of the first filter element, so that the effect of flushing the first filter element with the purified water produced by the second filter element is achieved, and the retention time T in this state is longer than the retention time T_{General assembly}2n (e.g., 30 seconds). After the first flushing state and the second flushing state are completed once, it is recorded as a cycle, and the cycle of repeating the first flushing state and the second flushing state is repeated for n times (for example, 5 times), and the flushing is completed. Thereby resetting the integration valve and adjusting the operation of the integration valve to an initial state (for example, the angle of the motor shaft is 0 °). In the whole washing process, the washing time is T_{General assembly}(e.g., 5 minutes).

Specifically, the fouling parameters include: current influent flow rate or current influent pressure.
