In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Example one
The embodiment provides a flushing control method, which is applied to a water purifying device, and particularly can be applied to a water purifying device with an integrated valve, and is combined with fig. 1, and the flushing control method comprises 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: the current water outlet flow value or the current water outlet pressure value. The current effluent flow value can be obtained through a flow detection device, preferably, the flow detection device can be a flowmeter or a flow sensor; a flow meter or flow sensor may be provided on the outlet line. The current water outlet pressure value can be acquired through a pressure detection device, preferably, the pressure detection device can be a pressure gauge or a pressure sensor, and the pressure gauge or the pressure sensor can be arranged on the water outlet pipeline.
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 fouling parameter is the current effluent flow value, the fouling threshold value may be set to the maximum flow value (e.g., 4.3l/min) flowing through the effluent pipeline when the flushing is required, and the person skilled in the art may also determine the fouling parameter according to actual needs. When the dirt blocking parameter is the current water outlet pressure value, the dirt blocking threshold value can be set to the maximum pressure value of the water outlet pipeline flowing through when the flushing is required, and the dirt blocking threshold value can also be determined by the technical personnel in the field according to the actual requirement. 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, controlling the opening and closing unit to act according to a preset flushing strategy when the dirt blocking parameter reaches a dirt blocking threshold value.
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 opening and closing unit.
The opening and closing unit can be in various forms such as a valve component, an integrated valve and a pipeline clamp, and is used for controlling the opening and closing state of the water inlet pipeline and/or the water outlet pipeline.
The washing control method provided by the embodiment comprises the steps of obtaining the dirt blocking parameter, judging whether the dirt blocking parameter reaches the dirt blocking threshold value, controlling the opening and closing unit to act according to the preset washing strategy after the dirt blocking parameter reaches the dirt blocking threshold value, determining the execution of the washing strategy according to the actual blocking condition of the filter element, ensuring the timeliness of the execution of the washing strategy, avoiding the condition of washing in advance or cleaning in a delayed mode, improving the accuracy of the execution of the washing strategy, and achieving the water saving effect on the basis of meeting the maximum service life of the filter element.
Specifically, when the dirty stifled parameter reaches dirty stifled threshold value, before control switching unit 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 composite filter element or a plurality of independent filter elements, the flushing mode is determined to be alternative flushing.
In this embodiment, the filter element form can be a single independent filter element, can also be a composite filter element, and can also be 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 composite filter element is adopted, at least two filter elements are arranged in parallel in one composite filter element, for simplifying the description, the two filter elements are arranged in parallel in one composite filter element as an example, and as the two filter elements are provided with the water inlet and the 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 the 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 composite 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 composite filter core, and no longer repeated here. Therefore, when the filter core is composite filter element or many independent filter elements, 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 composite filter element or a plurality of independent filter elements, after the flushing mode is determined to be 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 timeGeneral assembly；
Or acquiring the current water inlet pressure value;
based on the timeDetermining the flushing time T according to the corresponding relationship between the forward water inlet pressure value and the current water inlet pressure value and the flushing timeGeneral assembly。
In particular, the flushing time TGeneral assemblyIs composed of n times of flushing cycles, wherein each flushing cycle flushes one of the filter elements, and the retention time of each flushing cycle is TGeneral assembly/n。
As an implementation form, the flushing time TGeneral assemblyThe 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.
As another implementation, the flushing time TGeneral assemblyThe determination of the water inlet pressure value and the corresponding relation between the current water inlet pressure value and the flushing time are determined based on the obtained current water inlet pressure value and the corresponding relation between the current water inlet pressure value and the flushing time, the corresponding relation between the current water inlet pressure value and the flushing time can be measured before leaving a factory, a flow sensor is installed on a water path, the flow 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 the current water inlet pressure value needs to be acquired, the detected flow pulse number is transmitted to the controller, and the controller matches the detection value with the record value to find out the corresponding water inlet pressure.
Different water inlet pressure values P correspond to different flushing time T, and the larger the pressure is, the shorter the flushing time is. When the detected water inlet pressure value is P1, the corresponding filter element flushing time is T1 through program matching; when the detected water inlet pressure value is P2, the corresponding filter element flushing time is T2 through program matching; when the detected water inlet pressure value is P3, the corresponding filter element flushing time is matched to T3 through the program.
Furthermore, in order to improve the detection accuracy of the water inlet pressure value, the recorded data are detected for multiple times in the morning, in the evening, and when the detection values are within the set range value, the controller matches the detection values with the recorded values to determine the water inlet pressure value.
Specifically, the opening and closing unit includes an integration valve; when the dirty stifled parameter reaches dirty stifled threshold value, control switching unit carries out the action according to predetermineeing the strategy of washing, include:
adjusting the integrated valve to a first flushing state for a retention time TGeneral assembly/2n；
Adjusting the integrated valve to a second flushing state for a retention time TGeneral 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 opening and closing unit may be an integrated valve, and a motor is disposed on the integrated valve and drives the valve element to rotate, so as to adjust the opening and closing 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 is moved 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 flushed sewage can flow from the water inlet of the first filter elementThe water inlet of the second filter element is discharged, thereby realizing the effect of washing the second filter element by the purified water prepared by the first filter element, and the retention time T is in the stateGeneral assembly2n (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 TGeneral assembly2n (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 TGeneral assembly(e.g., 5 minutes).
