Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

In one embodiment, the application environment of the control method of the water purification apparatus provided by the present application may relate to both the water purification apparatus 102 and the external control apparatus 104, as shown in fig. 1. Wherein, the water purification unit 102 communicates with the external control unit 104 through network, protocol or bluetooth. Specifically, during the operation of the water purification apparatus 102, the external control apparatus 104 obtains the pump operation parameters of the water purification apparatus 102; calculating the pump operation variation of the water purification equipment 102 according to the pump operation parameters; the flushing parameters of the water purification apparatus 102 are adjusted based on the pump operation variation and the initial flushing parameters in the working process of the water purification apparatus 102, and the adjusted flushing parameters are obtained.

In one embodiment, the application environment of the control method of the water purification apparatus provided by the present application may only relate to the water purification apparatus 102. Wherein, a controller is arranged in the water purifying device 102. Specifically, in the working process of the water purification unit 102, the controller obtains the pump operation parameters of the water purification unit 102; calculating the pump operation variation of the water purification equipment 102 according to the pump operation parameters; based on the pump operation variation and the initial flushing parameter of the water purification apparatus 102 during the operation process, the flushing parameter of the water purification apparatus 102 is adjusted to obtain the adjusted flushing parameter, and the water purification apparatus 102 is controlled to flush according to the adjusted flushing parameter.

The water purifying device 102 may be a household water purifying device or a commercial water purifying device, the water purifying device 102 includes but is not limited to a cotton filter element water purifier, a reverse osmosis water purifier, an ultrafiltration water purifier, and the like, the controller in the water purifying device 102 may be a control circuit board or a control chip, the external control device 104 may be a terminal or a server, the terminal includes a smart phone, a tablet computer, a portable wearable device, and the like, and the server may be implemented by an independent server or a server cluster composed of a plurality of servers.

In one embodiment, as shown in fig. 2, a method for controlling a water purifying apparatus is provided, which is described by taking an example of the method applied to a controller of the water purifying apparatus 102 in fig. 1, and includes:

and S202, acquiring the pump operation parameters of the water purifying equipment in the working process of the water purifying equipment.

In one embodiment, the water purifying apparatus is an apparatus for producing purified water by using a reverse osmosis process, in which water flows from a low concentration to a high concentration, and the water flows from the high concentration to the low concentration after being pressurized, i.e., a principle of the reverse osmosis process, thereby filtering contaminants, scales, and the like in the water. The filter element of the water purifying device can be an activated carbon filter element, an ultrafiltration membrane filter element, a Reverse Osmosis membrane filter element (RO) and the like. The water purifying equipment further comprises a water pump, and the water pump can be specifically a booster pump, including but not limited to a gas-liquid booster pump, a gas booster pump, an air booster pump, a chlorine booster pump and the like, and can be selected according to the actual application of the water purifying equipment.

In one embodiment, the pump operation parameter refers to an operation parameter of a water pump of the water purification apparatus, including but not limited to a current and a rotation speed of the water pump, which are respectively referred to as a pump current and a pump rotation speed, i.e. the pump operation parameter includes at least one of the pump current and the pump rotation speed. Along with the increase of the water filtration quantity of the water purification equipment or the change of water quality, pollutants and water scales in water can cause the filter element of the water purification equipment to be blocked, so that the operation parameters of the pump are changed, namely the operation parameters of the pump can reflect the real-time blocking condition of the filter element of the water purification equipment, and the filter element is washed. Generally, a wastewater electromagnetic valve of the water purifying equipment is opened by controlling, a water inlet electromagnetic valve is controlled to be electrified, and a water pump is controlled to be electrified, so that a filter element of the water purifying equipment is washed.

Theoretically, along with the gradual blockage of the filter element of the water purifying equipment, the pump current can be gradually increased, and the pump rotating speed can be gradually reduced. Therefore, the water purifying equipment can determine the real-time blocking condition of the filter element according to the pump operation parameters, and further determine whether to flush the filter element or not so as to prolong the service life of the filter element and achieve the effect of saving water. Specifically, in the working process of the water purifying equipment, the pump operation parameters of the water purifying equipment are obtained. The working circuit of the water pump of the water purification device can be provided with a pump operation parameter detection component, specifically, a current detection component and a rotation speed detection component, such as an ammeter, a tachometer, a current sensor, a rotation speed sensor and the like, so as to detect and obtain the pump operation parameter, that is, detect and obtain the pump current and the pump rotation speed.

In one embodiment, since the detection time of the pump operation parameter detection assembly is short, the obtained pump operation parameters include a plurality of pump operation parameters, specifically, the pump operation parameters detected at each detection time point may be the pump operation parameters detected at each detection time point, and the pump operation parameters detected at each detection parameter point may also be the pump operation parameters detected at each detection time point. When the pump operation parameters obtained at the detection time points are detected, the time intervals between the detection time points may be the same or different. For example, 4 pump operation parameters are obtained, and if the pump operation parameters are detected respectively at 10 minutes, 20 minutes, 30 minutes and 40 minutes of water purification in the water purification apparatus, the time intervals between the detection time points are the same. If the detection time points are detected respectively when the water purifying equipment purifies water for 10 minutes, 11 minutes, 20 minutes and 26 minutes, the time intervals among the detection time points are different, namely the detection time points are random detection time points. Wherein, the detection parameter point can be confirmed according to the water purification volume, specifically can be for detecting the water purification volume point, when detecting at each detection water purification volume point and obtaining pump operating parameter, the water purification volume difference value between each detection water purification volume point can be the same, also can not be the same. For example, 4 pump operation parameters are obtained, and if the pump operation parameters are detected respectively at 10 liters, 20 liters, 30 liters and 40 liters of purified water in the water purifying device, the purified water amount difference values between the detected purified water amount points at the moment are the same. If the difference values are detected respectively in 10 liters, 11 liters, 20 liters and 26 liters of purified water of the water purifying equipment, the purified water quantity difference values between the detected purified water quantity points are different, namely the detected purified water quantity points are random detected purified water quantity points.

In one embodiment, when the water purification equipment is produced, the washing conditions for washing the filter element are preset, and the washing conditions preset for different water purification equipment are different. The preset flushing condition can be a preset water purification time length or a preset water purification amount, and the flushing parameters contained in the preset flushing condition are called as initial flushing parameters. Specifically, the initial flush parameters may include any one of an initial flush interval, an initial single flush duration, an initial flush voltage, and an initial flush pump speed. And if the water purifying time of the water purifying equipment reaches the preset water purifying time or the water purifying quantity of the water purifying equipment reaches the preset water purifying quantity, the preset flushing condition of the water purifying equipment is determined to be reached. Therefore, if the washing condition corresponding to the initial washing parameter is reached, the water purification equipment is controlled to wash according to the initial washing parameter, and the subsequent calculation processing steps are continuously executed after washing. In addition, if the washing condition corresponding to the initial washing parameter is not reached, the subsequent calculation processing steps are directly continued to be executed.

And step S204, calculating the pump operation variation of the water purifying equipment according to the pump operation parameters.

In one embodiment, the pump operation variation of the water purification unit is calculated according to the pump operation parameters. The variable quantity of the pump operation parameters can reflect the speed of the change of the pump operation parameters, namely the real-time blockage condition of the filter element. The pump operation variation can be a difference value of two pump operation parameters, and the two pump operation parameters at the moment can be pump operation parameters obtained by detecting time points or pure water amount points at any two times, can be adjacent two times, and can also be nonadjacent two times. For example, when the pump operation variation is a difference between the pump operation parameters corresponding to any two detection time points, 4 pump operation parameters are obtained and detected when the water purifying equipment purifies water for 10 minutes, 20 minutes, 30 minutes and 40 minutes, respectively, and when the pump operation variation is calculated, the difference between the pump operation parameters corresponding to the water purifying equipment purifies water for 10 minutes and 20 minutes may be calculated, or the difference between the pump operation parameters corresponding to the water purifying equipment purifies water for 10 minutes and 30 minutes may be calculated. For example, when the pump operation variation is the difference between the pump operation parameters corresponding to the detected water purification amount points at any two times, 4 pump operation parameters are obtained and detected at 10 liters, 20 liters, 30 liters and 40 liters of purified water of the water purification apparatus, respectively, and when the pump operation variation is calculated, the difference between the pump operation parameters corresponding to 10 liters and 20 liters of purified water of the water purification apparatus may be calculated, or the difference between the pump operation parameters corresponding to 10 liters and 30 minutes of purified water of the water purification apparatus may be calculated.

In one embodiment, the pump operating parameter includes at least one of pump current and pump speed. If the pump operation parameter is the pump current, the pump operation variation is the pump current variation, i.e. the difference between the two pump currents. If the pump operation parameter is the pump rotation speed, the pump operation variation is the pump rotation speed variation, that is, the difference between the two pump rotation speeds.

Wherein, if the obtained pump currents are respectively in the water purifying device for purifying water T₁Pump current A detected by duration₁And in the water purification unit₂Pump current A detected by duration₂Or, if the obtained pump current is respectively the water purified Q in the water purifying equipment₁Pump current A detected by liter₁And in the water purification equipment water purification Q₂Pump current A detected by liter₂If the pump current variation Δ a is greater than the pump current variation Δ a, the calculation formula is:

ΔA＝A₂-A₁

wherein, ifThe obtained pump rotating speeds are respectively at the water purifying T of the water purifying equipment₁Pump speed R obtained by duration detection₁And in the water purification unit₂Pump speed R obtained by duration detection₂Or if the obtained pump rotating speeds are respectively the water purification Q of the water purification equipment₁Pump speed R measured in liters₁And in the water purification equipment water purification Q₂Pump speed R measured in liters₂If the pump speed variation Δ R is greater than the preset value, the calculation formula is as follows:

ΔR＝R₂-R₁

in one embodiment, the pump operation variation may also be a pump operation parameter variation coefficient corresponding to the pump operation parameter, where the pump operation parameter variation coefficient may be obtained by calculation according to the pump operation parameter and a water purification parameter corresponding to the pump operation parameter, that is, the pump operation variation may also be a pump operation parameter variation coefficient of the water purification apparatus obtained by calculation according to each pump operation parameter and a water purification parameter corresponding to each pump operation parameter. Specifically, the water purification parameters of the water purification apparatus include at least one of a water purification duration and a water purification amount.

In particular, as the water purification apparatus is continuously operated, the pump operation parameters are continuously detected and acquired. Wherein, the mode of calculating the pump operation parameter variation coefficient who obtains water purification unit includes: determining water purification parameters of the water purification equipment corresponding to the operation parameters of each pump; determining an average water purification parameter and an average pump operation parameter according to the pump operation parameters and the water purification parameters respectively; and calculating to obtain the pump operation parameter variation coefficient of the water purification equipment according to the operation parameter difference value of each pump operation parameter and the average pump operation parameter and the water purification parameter difference value of each water purification parameter and the average water purification parameter. Specifically, the pump operation parameter variation coefficient is a ratio of the sum of products of each operation parameter difference and the corresponding water purification parameter difference to the sum of squares of each water purification parameter difference.

In one embodiment, if the pump operation parameter is a pump current, the pump operation variation is a pump current variation coefficient. Because the pump current is gradually increased along with the gradual blockage of the filter element of the water purifying equipment, the change coefficient of the pump current is the increase coefficient of the pump current,the magnitude of which can reflect how fast the pump current increases. Wherein, the time length of the water purification equipment corresponding to the pump current is determined, and if the obtained pump currents are water purification T of the water purification equipment respectively₁Pump current A detected by duration₁In water purification equipment water purification T₂Pump current A detected by duration₂Until the water purification T of the water purification equipment_iPump current A detected by duration_i。

In one embodiment, the water purification amount of the water purification device corresponding to the pump current is determined, and if the obtained pump currents are respectively the water purification Q in the water purification device₁Pump current A detected by liter₁In the water purifying equipment, the water Q is purified₂Pump current A detected by liter₂Until the water is purified in the water purifying equipment Q_iPump current A detected by liter_i。

the pump current variation coefficient is the ratio of the sum of products of each pump current difference value and the corresponding purified water quantity difference value to the sum of squares of each purified water quantity difference value.

In one embodiment, if the pump operation parameter is a pump speed, the pump operation variation is a pump speed variation coefficient. As the filter element of the water purifying equipment is gradually blocked, the rotating speed of the pump can be gradually reduced, so that the change coefficient of the rotating speed of the pump is the attenuation coefficient of the rotating speed of the pump, and the reduction speed of the rotating speed of the pump can be reflected by the change coefficient of the rotating speed of the pump. Determining the water purification duration of the water purification equipment corresponding to the pump rotating speed, and if the obtained pump rotating speeds are water purification T of the water purification equipment respectively₁Pump speed R obtained by duration detection₁In water purification equipment water purification T₂Pump speed R obtained by duration detection₂Until the water purification T of the water purification equipment_iPump speed R obtained by duration detection_i。

the pump rotating speed variation coefficient is the ratio of the sum of the products of the pump rotating speed difference values and the corresponding water purification time length difference values to the sum of squares of the water purification time length difference values.

In one embodiment, the purified water amount of the water purification device corresponding to the pump rotation speed is determined, and if the obtained pump rotation speeds are respectively the purified water Q in the water purification device₁Pump speed R measured in liters₁In the water purifying equipment, the water Q is purified₂Pump speed R measured in liters₂Until the water is purified in the water purifying equipment Q_iPump speed R measured in liters_i。

The calculation formula is as follows:

The calculation formula is as follows:

the pump rotating speed variation coefficient is the ratio of the sum of the products of the pump rotating speed difference values and the corresponding purified water quantity difference values to the sum of squares of the purified water quantity difference values.

It should be noted that the pump operation variation may be determined according to a single type of pump operation parameter, for example, the pump current variation, the pump speed variation, the pump current variation coefficient, and the pump speed variation coefficient are determined according to the pump current and the pump speed, respectively. In addition, the pump operation variation may also be determined synthetically from various types of pump operation parameters, for example, from the pump current and the pump speed, the corresponding pump operation variation being determined synthetically. Specifically, a functional relationship among various types of pump operation parameters is established in advance, and the pump operation variation is determined comprehensively.

And S206, adjusting the flushing parameters of the water purifying equipment based on the pump operation variable quantity and the initial flushing parameters in the working process of the water purifying equipment to obtain the adjusted flushing parameters.

In one embodiment, in order to adapt the flushing parameters to the real-time blocking condition of the filter element of the water purifying equipment and take the flushing effect and the water saving requirement into consideration, the initial flushing parameters in the working process of the water purifying equipment need to be adjusted, and then the filter element of the water purifying equipment is flushed. The adjusted initial flushing parameters are referred to as adjusted flushing parameters. Specifically, since the pump operation variation reflects the real-time blockage of the filter element, the initial flushing parameter can be adjusted according to the calculated pump operation variation.

In one embodiment, the initial flushing parameter includes a preset first variation and a preset second variation, wherein the first variation is greater than or equal to the second variation. The amount of pump operation variation is compared to the amount of variation contained in the initial flush parameters. In the comparison, the pump operation variation amount needs to be compared with a corresponding variation amount. For example, if the pump operation variation is the pump current variation, the pump operation variation is compared with the pump current variation included in the initial flushing parameter. And if the pump operation variation is the pump current variation coefficient, comparing the pump operation variation with the pump current variation coefficient contained in the initial flushing parameter.

In one embodiment, if the pump operation variation is greater than the first variation, it indicates that the real-time blocking speed of the filter element is faster, and if the filter element is flushed according to the initial flushing parameters, the flushing effect is poor. Thus, the first flush parameter may be set to the adjusted post-flush parameter. When the initial flushing parameters are adjusted, the initial flushing parameters can be directly switched to the first flushing parameters, or the initial flushing parameters can be gradually adjusted to the first flushing parameters. The first flushing parameter includes any one of a first flushing interval, a first single flushing duration, a first flushing voltage, and a first flushing pump rotational speed. Specifically, the first flushing interval is smaller than the initial flushing interval in the initial flushing parameters, the first single flushing duration is longer than the initial single flushing duration in the initial flushing parameters, the first flushing voltage is longer than the initial flushing voltage in the initial flushing parameters, and the first flushing pump rotation speed is longer than the initial flushing pump rotation speed in the initial flushing parameters.

The first flushing interval is a time interval after the initial flushing interval is shortened by a first proportion, and the first proportion can be a preset proportion and is expressed as a%. The first single rinsing duration is a duration of the initial single rinsing duration increased by a third proportion, which may be a preset proportion, expressed as b%. The first rinsing voltage is a voltage obtained by increasing the initial rinsing voltage by a fifth proportion, which may be a preset proportion and is expressed as c%. The first flush pump speed is the pump speed after the initial flush pump speed is increased by a seventh proportion, which may be a preset proportion, expressed as d%.

In one embodiment, if the pump operation variation is smaller than the second variation, it indicates that the real-time blocking speed of the filter element is slow, and if the filter element is flushed according to the initial flushing parameters, the waste of flushing water is caused. Thus, the second flush parameter may be set to the adjusted post-flush parameter. When the initial flushing parameters are adjusted, the initial flushing parameters can be directly switched to the second flushing parameters, or the initial flushing parameters can be gradually adjusted to the second flushing parameters. The second flushing parameter comprises any one of a second flushing interval, a second single flushing time length, a second flushing voltage and a second flushing pump rotating speed. Specifically, the second flushing interval is greater than the initial flushing interval in the initial flushing parameters, the second single flushing duration is less than the initial single flushing duration in the initial flushing parameters, the second flushing voltage is less than the initial flushing voltage in the initial flushing parameters, and the second flushing pump rotation speed is less than the initial flushing pump rotation speed in the initial flushing parameters.

Wherein the second flushing interval is a time interval after the initial flushing interval is increased by a second proportion, and the second proportion may be a preset proportion, which is denoted as e%. The second single rinsing duration is a duration of the initial single rinsing duration reduced by a fourth proportion, which may be a preset proportion, expressed as f%. The second flushing voltage is a voltage obtained by reducing the initial flushing voltage by a sixth proportion, and the sixth proportion can be a preset proportion and is expressed as g%. The second washing pump rotation speed is the pump rotation speed after the initial washing pump rotation speed is reduced by an eighth proportion, and the eighth proportion can be a preset proportion and is expressed as h%. It should be noted that, the data values of the first proportion and the second proportion, the third proportion and the fourth proportion, the fifth proportion and the sixth proportion, and the seventh proportion and the eighth proportion may be the same or different, and may be specifically limited according to the actual situation of the water purification apparatus.

And S208, controlling the water purifying equipment to flush according to the adjusted flushing parameters.

In one embodiment, after the adjusted washing parameters are obtained, the water purification equipment is controlled to wash the filter element of the water purification equipment according to the obtained adjusted washing parameters, so that the washing effect is improved, and the requirement of saving water is met. Specifically, the waste water electromagnetic valve of the water purifying device is controlled to be opened, the water inlet electromagnetic valve is controlled to be electrified, and the water pump is controlled to be electrified, so that the filter element of the water purifying device is washed.

In the control method of the water purification equipment, the pump operation parameters of the water purification equipment are obtained in the working process of the water purification equipment; calculating the pump operation variable quantity of the water purifying equipment according to the pump operation parameters; adjusting the flushing parameters of the water purification equipment based on the pump operation variation and the initial flushing parameters in the working process of the water purification equipment to obtain the adjusted flushing parameters; and controlling the water purification equipment to flush according to the adjusted flushing parameters. By adopting the method of the embodiment, the flushing program of the water purifying equipment can be adjusted according to the real-time blocking condition of the filter element in the working process of the water purifying equipment, so that the flushing program can adapt to the water quality of the area where the water purifying equipment is located, the flushing effect and the water saving requirement are both considered, the automatic adjustment of the flushing program of the water purifying equipment is realized, and the flushing efficiency of the water purifying equipment can be improved.

Fig. 3 is a schematic flow chart showing a control method of the water purifying apparatus executed by the controller, which includes the following steps:

the water purifying equipment starts to work, and at least one of pump current and pump rotating speed in the working process of the water purifying equipment is obtained;

if the water purifying time of the water purifying equipment reaches the preset water purifying time or the water purifying amount reaches the preset water purifying amount, determining that the preset flushing condition of the water purifying equipment is reached, and controlling the water purifying equipment to flush according to the initial flushing parameters;

if the situation that the preset flushing condition of the water purifying equipment is not met is determined, calculating the pump operation variation of the water purifying equipment according to the pump operation parameters, and adjusting the flushing parameters of the water purifying equipment based on the pump operation variation and the initial flushing parameters in the working process of the water purifying equipment to obtain the adjusted flushing parameters; wherein, the pump operation variable quantity is the difference of the pump operating parameter twice, or, the pump operation variable quantity is according to each pump operating parameter to and the water purification parameter that each pump operating parameter corresponds, calculates the pump operating parameter coefficient of change of the water purification unit who obtains, specifically includes:
