Example one
Fig. 1 is a schematic flow chart of a water softening method according to an embodiment of the present invention, which is applicable to water softening and the like, and the method may be implemented by a water softening device according to an embodiment of the present invention, where the device may be implemented by software and/or hardware, and in a specific embodiment, the device may be integrated in an electronic device. The following embodiments will be described by taking as an example that the apparatus is integrated in an electronic device, and referring to fig. 1, the method specifically includes the following steps:
s101, obtaining the total amount of soluble solids of raw water in the water softener.
The water softener is an instrument for softening the hardness of raw water, and particularly, the water softener can exchange calcium ions and magnesium ions in hard water through sodium ions in ion exchange resin in the water softener, so that the hardness of the water is reduced, and soft water is obtained.
Specifically, the Total Dissolved Solids (TDS) of the raw water is understood as the Total content of dissolved solids in the raw water in mg/l, and a higher value of TDS indicates more dissolved matter in the water. The water softener provided by the embodiment of the invention is internally provided with the TDS probe, the probe can be arranged at the water inlet pipe of raw water, and when the raw water flows through the TDS probe, the TDS probe can detect the total dissolved solid content of the raw water.
The advantage of setting up like this lies in can acquireing the dissoluble solid total amount of raw water in real time, no matter what kind of change takes place for the TDS value of raw water, all can confirm accurate dissoluble solid total amount in the very first time.
And S102, determining the cumulative hardness of the raw water according to the total amount of the soluble solids.
The accumulated hardness is the total hardness of the raw water softened in the soft water period, and can be used for measuring the progress of the soft water and the residual soft water amount in the soft water period.
Specifically, the total soluble solid content of the raw water and the hardness have a corresponding relation, and after the total soluble solid content of the raw water is determined, the hardness of the raw water can be determined according to the corresponding relation between the total soluble solid content and the hardness; the accumulated hardness is the sum of the hardness of the raw water softened in the soft water period.
For example, if the raw water is softened five times in the soft water period and the water hardness is a, B, C, D and E, respectively, the cumulative hardness of the raw water is a + B + C + D + E.
According to the embodiment of the invention, the water quality hardness of the raw water can be rapidly and accurately determined by searching the corresponding relation table of the total soluble solid and the hardness.
And S103, controlling the ion exchange resin in the water softener to regenerate when the accumulated hardness meets a preset hardness condition and/or the service time of the ion exchange resin in the water softener meets a preset time condition so as to soften the water quality based on the regenerated resin.
The ion exchange resin is a tool for exchanging calcium and magnesium ions in raw water by a water softener, the ion exchange resin can be saturated and invalid after being used for a period of time, the calcium and magnesium ions adsorbed on the resin are removed by salt addition reverse reaction, the resin is regenerated, and the regeneration time of the ion exchange resin refers to the time for the resin to be saturated and the resin to be regenerated by the salt addition reverse reaction.
The preset hardness can be understood as the total hardness of raw water which can be softened in a soft water period, and the ion exchange resin is completely saturated at this time; the preset time may be a time for regenerating the ion exchange resin set according to a user's requirement, in which case the ion exchange resin may not be completely saturated, but the ion exchange resin is regenerated periodically in order to better soften water in the water softener. The embodiment of the present invention does not limit this.
Specifically, the periodic soft water hardness of the water softener can be obtained according to the relation among the hardness value of raw water of the water softener, the effective resin filling amount and the resin working exchange capacity, the periodic soft water hardness can be understood as the corresponding preset hardness of the water softener, when the accumulated hardness meets the preset hardness condition, the ion exchange resin is saturated, the salt adding reverse reaction can be carried out on the soft water, calcium and magnesium ions adsorbed on the resin are removed, and the ion exchange resin is regenerated. The regeneration time of the ion exchange resin can be set according to the soft water requirement of a user, the regeneration time can be understood as the corresponding preset time of the water softener, and the set regeneration time of the ion exchange resin is assumed to be 48 hours, so that when the service time of the ion exchange resin in the water softener reaches 48 hours, the soft water can carry out reverse reaction of adding salt, calcium and magnesium ions adsorbed on the resin are removed, and the ion exchange resin is regenerated.
Specifically, when the use time of the ion exchange resin in the water softener reaches the preset time but the ion exchange resin is not saturated, the salt amount and the water amount of the regenerated ion exchange resin can be calculated according to the use condition of the ion exchange resin, and the salt adding reverse reaction is carried out according to the corresponding salt amount and water amount, so that the waste of resources is reduced.
The embodiment of the invention sets two methods for controlling the regeneration of the ion exchange resin in the water softener, and can match a proper regeneration method according to the actual soft water requirement. For example, when the soft water demand is high, the accumulated hardness can satisfy the preset hardness condition first, and when the soft water demand is low, the resin regeneration needs to be controlled at the set time, so as to improve the soft water effect of the water softener and save the salt resource.
According to the technical scheme of the embodiment, the total amount of soluble solids of raw water in the water softener is obtained; determining the cumulative hardness of the raw water according to the total amount of the soluble solids; and when the accumulated hardness meets the preset hardness condition and/or the service time of the ion exchange resin in the water softener meets the preset time condition, controlling the ion exchange resin in the water softener to regenerate so as to soften the water quality based on the regenerated resin. The invention can detect the total dissolved solids of the raw water at regular time and determine the water hardness of the raw water by combining the regional information and the time information, namely dynamically determining the water hardness of the raw water of the water softener and the regeneration time of the ion exchange resin, thereby leading the determined regeneration time of the ion exchange resin to be more matched with the actual water hardness, and reducing the problems of waste of regenerated salt or poor water softening effect and the like caused by determining the regeneration time of the ion exchange resin of the water softener by adopting the fixedly arranged water hardness.

Wherein, the accumulated hardness is the sum of the current hardness and the historical data corresponding to the current hardness.
The current hardness is the hardness of the raw water measured this time, that is, the hardness corresponding to the total amount of the soluble solids detected by the TDS probe. The total soluble solid content of the raw water is measured for multiple times in the soft water period, the total soluble solid content measured each time corresponds to one current hardness, and the accumulated hardness is the sum of all current hardnesses in the period.
Illustratively, if the total amount of soluble solids is measured five times in the soft water cycle, the corresponding water hardness values are a, B, C, D, and E, respectively, and the current hardness value measured this time is E. Then, the historical data corresponding to the current hardness in the soft water period are A, B, C and D, and the accumulated hardness is A + B + C + D + E.
