Example 1
Fig. 1 is a schematic flow chart of a water softening method according to an embodiment of the present invention, where the embodiment is applicable to water softening, and the method may be performed by a water softening device according to an embodiment of the present invention, and the device may be implemented in software and/or hardware, and in a specific embodiment, the device may be integrated in an electronic device. The following embodiment will be described taking the example of the integration of the apparatus 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 specifically, the water softener can exchange calcium and magnesium ions in hard water through sodium ions in ion exchange resin in the water softener, so that the hardness of water quality is reduced, and soft water is obtained.
Specifically, the total amount of soluble solids (Total dissolved solids, TDS) of raw water is understood to be the total amount of soluble solids in raw water in milligrams per liter, with higher TDS values indicating more soluble matter contained in 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 raw water flows through the TDS probe, the TDS probe detects the total amount of dissolved solids of the raw water.
The advantage of this arrangement is that the total amount of dissolved solids of the raw water can be obtained in real time, and the exact total amount of dissolved solids can be determined at the first time, no matter what the TDS value of the raw water changes.
S102, determining the accumulated 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 soft water progress and the residual soft water quantity in the soft water period.
Specifically, the total amount of soluble solids of raw water has a corresponding relation with the hardness, and after the total amount of soluble solids of raw water is determined, the hardness of the raw water can be determined according to the corresponding relation between the total amount of soluble solids 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 soft water is softened five times in the present soft water period, the water hardness is A, B, C, D and E, respectively, and the accumulated hardness of the raw water is a+b+c+d+e.
According to the embodiment of the invention, the water hardness of raw water can be rapidly and accurately determined by searching the corresponding relation table of the total amount of the soluble solids and the hardness.
And S103, 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 regeneration of the ion exchange resin in the water softener 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 of the water softener, the ion exchange resin is saturated and invalid after being used for a period of time, the calcium and magnesium ions adsorbed on the resin are removed through salt adding reverse reaction, the resin is regenerated, and the regeneration time of the ion exchange resin refers to the time for regenerating the resin through salt adding reverse reaction when the ion exchange resin is saturated.
The preset hardness is understood to be the total hardness of raw water that can be softened in one soft water cycle, at which time the ion exchange resin is completely saturated; the preset time may be a time for regenerating the ion exchange resin set according to the user's demand, in which case the ion exchange resin may not be completely saturated, but the ion exchange resin is periodically regenerated in order to make the water softener soften water better. The embodiment of the present invention is not limited thereto.
Specifically, the cycle 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 cycle 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 water softener can perform salt adding reverse reaction, 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 48 hours, so that when the service time of the ion exchange resin in the water softener reaches 48 hours, the water softener can carry out salt adding reverse reaction, thereby removing calcium and magnesium ions adsorbed on the resin and regenerating the ion exchange resin.
Specifically, when the service 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 are calculated according to the service 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 be matched with 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, and when the soft water demand is low, the regeneration of the resin needs to be controlled at a set time so as to improve the soft water effect of the water softener, and meanwhile, the salt resource is saved.
According to the technical scheme, the total amount of dissolved solids of raw water in the water softener is obtained; determining the accumulated 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 regeneration of the ion exchange resin in the water softener to soften the water quality based on the regenerated resin. The invention can detect the total amount of the soluble solids of the raw water at fixed time, and determine the water quality hardness of the raw water by combining the area information and the time information, namely dynamically determining the water quality hardness of the raw water of the water softener and the regeneration time of the ion exchange resin, so that the determined regeneration time of the ion exchange resin is more matched with the actual water quality hardness, and the problems of waste of regenerated salt or poor water quality softening effect caused by the fact that the fixed water quality hardness is adopted to determine the regeneration time of the ion exchange resin of the water softener are reduced.
Example two
Fig. 2 is a schematic flow chart of a water softening method according to a second embodiment of the present invention, where the method is applicable to water quality monitoring and softening, and the method may be performed by a water softening device according to the second embodiment of the present invention, and the device may be implemented in software and/or hardware, and in a specific embodiment, the device may be integrated in an electronic device. The following embodiment will be described taking the example of the integration of the device in an electronic apparatus, and referring to fig. 2, the method specifically includes the following steps:
s201, 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 specifically, the water softener can exchange calcium and magnesium ions in hard water through sodium ions in ion exchange resin in the water softener, so that the hardness of water quality is reduced, and soft water is obtained. Specifically, the total amount of soluble solids (Total dissolved solids, TDS) of raw water is understood to be the total amount of soluble solids in raw water, and the higher the TDS value, the more soluble substances contained in 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 raw water flows through the TDS probe, the TDS probe detects the total amount of dissolved solids of the raw water, so that the total amount of the dissolved solids of the raw water can be obtained in real time.
S202, acquiring position information and time information of the water softener, and determining a corresponding table of the relation between the total amount of the soluble solids and the hardness, which corresponds to the position information and the time information.
The position information of the water softener can be understood as the information of the water fountain, and the time information can be understood as the time for measuring the total amount of dissolved solids of the raw water.
Specifically, the raw water of the water softener comprises hard water which is not subjected to calcium and magnesium ion exchange, for example, the raw water can be natural water sources which are not subjected to any artificial purification treatment in the nature such as groundwater, spring water, reservoir water and the like, or can be tap water which is subjected to precipitation, filtration, disinfection, entering a clean water reservoir and then is conveyed to a user's home through a water conveying and distributing pipeline, the hardness detection of the raw water is an index for analyzing the quality of the raw water, and the hardness of the raw water input into the water softener is different in different areas and different seasons.
The method comprises the steps of dividing areas in advance, collecting water samples of each area in different time periods, and carrying out assay and data fitting to obtain the corresponding relation between TDS and water hardness in different areas and at different times. When the method is actually applied, after the position information and the time information are determined, a corresponding table of the relation between the total amount of the soluble solids and the hardness can be directly called so as to quickly and accurately determine the hardness of the raw water.
S203, determining the accumulated hardness of the raw water according to the total dissolved solids and a corresponding table of the relation between the total dissolved solids and the hardness.
The accumulated hardness is the total hardness of the raw water softened in the soft water period, and can be used for measuring the soft water progress and the residual soft water quantity in the soft water period.
Specifically, after the total amount of the soluble solids of the raw water and the corresponding table of the relation between the total amount of the soluble solids and the hardness are determined, the hardness of the raw water can be determined; the accumulated hardness is the sum of the hardness of the raw water softened in the soft water period.
