Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Along with the improvement of the health and safety requirements of users on drinking water, the water purifier is favored by the vast users. The water purifier can purify tap water through the purification filter element so as to achieve the purpose of purifying water. The small-flow water purifier has the advantages of low water making speed, long water receiving waiting time of a user and poor user experience; the large-flow water purifier is a development trend of industry and can realize instant preparation and instant drinking.

At present, the maximum flow of a single filter element in the industry is 1200G, and in order to realize the flow requirements of water purification with larger flow or other small flows, a plurality of small-flow filter elements are commonly used in parallel in the industry. However, the service life of different filter elements on the parallel water path is different, so that the problem of core replacement is caused, and if one filter element fails, the other filter element is replaced synchronously, so that the cost of replacing the filter elements is wasted.

If one filter element is invalid, the other filter element is replaced when the other filter element is invalid, and the filter element is replaced for a plurality of times, so that the filter element replacement cost is increased, and inconvenience is brought to later maintenance. Therefore, it is necessary to find a method for achieving the synchronous failure of the filter element.

The service life of the filter element is inversely related to the flow, and the service life of the filter element is longer when the flow is smaller; the greater the flow rate, the more membrane fouling is accelerated resulting in a shorter cartridge life.

The membrane pollution condition can be reflected by the attenuation coefficient of the filter element, and the greater the attenuation coefficient is, the more serious the membrane pollution is. When the attenuation coefficient of the filter element is within the set limit value range, the filter element can be invalid at a set time; if the attenuation coefficient of the filter element exceeds a preset limit value, the filter element fails in advance due to the aggravation of membrane pollution, so that 2 filter element failure time points are different, and the later maintenance is inconvenient.

For the analysis, a way is needed to adjust the load of the filter element so as to realize the synchronous failure of the filter element.

The maintenance of the existing filter element mainly improves the maintenance period of the filter element by adding a standby filter element, CN103951094A reports a water purifier convenient to maintain, and when the service life of the short-period filter element is prolonged and the maintenance is not timely carried out after sale, the normal operation of the water purifier is ensured, but the patentability is read, and the volume of the water purifier is increased by adding the standby filter element into the water purifier.

CN105692732a reports a method and a device for adjusting the service life of a filter element of a water purifier, which adjusts the maximum value of the service life of the filter element by detecting the effective TDS value and the water production time before a membrane, reflects the real service life of the filter element to save the cost of replacing the filter element, but reads the patentability of the device, only introduces a method for detecting the real service life of the filter element, and cannot adjust the service lives of different filter elements to realize synchronous failure.

Through the analysis, the method is an important breakthrough if a feasible technical scheme can be provided for adjusting the load of the filter element to realize synchronous failure of different filter elements. The technical scheme aims at providing a method for adjusting the service life of a filter element of a water purifier, and solves the problem of frequent core replacement caused by different service life periods of different filter elements.

The controller calculates the attenuation coefficient of the corresponding filter element according to the flow value of 2L/min, and the attenuation coefficient is specifically as follows:

When the real-time attenuation coefficients corresponding to the 600G filter element and the 800G filter element are detected to be 0.02 and 0.02, the system does not need to adjust the diverter valve 151, and the passing flow of the 600G filter element and the 800G filter element is 1.5L/min and 2L/min.

When the real-time attenuation coefficients corresponding to the 600G filter element and the 800G filter element are detected to be 0.04 and 0.02, correspondingly, the flow rate of the purified water passing through the 600G filter element is increased from 1.5L/min to 21L/min, and the flow rate of the purified water passing through the 800G filter element is decreased from 2.1L/min to 1.4L/min.

At this time, the system controls the opening and closing degree of the diverter valve 151 to reduce the proportion of the inflow water flow corresponding to the 600G filter element, so that the proportion of the inflow water flow passing through the 800G filter element is increased, and the corresponding pure water flows of the 600G filter element and the 800G filter element are 1.5L/min and 2L/min respectively.

More specifically, as shown in fig. 3, the diverter valve 151 may be replaced with a single flow regulator valve 152 positioned in one of the branches to regulate the flow load on that branch.

Similarly, as shown in fig. 4, the diverter valve 151 may be replaced with two flow regulating valves 152 placed on two branches to regulate the branch flow.

Likewise, the flow dividing valve 151 may adjust the flow ratio by adjusting the output power of the pump.

According to an embodiment of the present utility model, in another aspect, there is also provided a storage medium storing a computer program which, when executed by a processor, implements the steps of the water production control method of the water purification system 100 of any one of the above.

Specifically, the storage medium stores a computer program, which when executed by a processor, can implement the following steps:

the ratio of the inflow water flow of the flow regulator 150 is adjusted according to the attenuation coefficient.

The storage medium may further perform the steps of:

If the attenuation coefficient is lower than the lower limit value of the set threshold value, the flow regulation is not needed;

And if the attenuation coefficient is higher than the lower limit value of the set threshold value, regulating the flow value of the corresponding first filter element to reduce the load of the first filter element.
