In addition, a water level detecting device is further provided on the steam generator for detecting the water level in the steam generator.
In order to explain how to control the water softening system in the washing machine provided by the embodiment of the present invention in detail, in another embodiment of the present invention, with reference to the above embodiment, as shown in fig. 2, there is also provided a method for controlling the water softening system in the washing machine, where the method specifically includes the following steps:
and step S110, acquiring the total amount of calcium and magnesium ions in the water of the water softening system.
Specifically, as shown in fig. 3, the total amount of calcium and magnesium ions in the water of the water softening system can be obtained by:
and step S111, calculating the water inflow in the water softening system, wherein the water inflow of the water softening system is the water inflow of each time from the last time of regeneration treatment of the water softener to the current period.
And step S112, calculating the total amount of calcium and magnesium ions in the water of the water softening system by detecting the concentration and the water inflow of the calcium and magnesium ions in the water.
The embodiment of the invention can obtain the water quantity of the water to be softened in the water softening system by detecting the total water inflow and the water discharge of the water softening system, and detect the hardness of the water in the water softening system by the hardness detection device 1 and the hardness detection device 2 which are arranged on the water box 1 and the water box 2.
And step S120, acquiring the treatment capacity of the water softener for treating calcium and magnesium ions in water.
In the embodiment of the invention, the detection of the water hardness mainly comprises the steps of detecting the content of calcium and magnesium ions in water, and treating the calcium and magnesium ions in the water through an ion exchange resin filled in a water softener. Because the ion exchange resin in unit volume can only process preset unit calcium and magnesium ions, the upper limit value of the calcium and magnesium ions in the processing water can be calculated by the ion exchange resin in the water softener, and then whether the water softener can completely soften the water in the water softening system is determined.
Step S130, judging whether the treatment capacity of the water softener for treating calcium and magnesium ions in water is less than the total amount of the calcium and magnesium ions in the water of the water softening system.
And step S140, if the treatment capacity of the water softener for treating calcium and magnesium ions in water is less than the total amount of the calcium and magnesium ions in the water of the water softening system, performing regeneration treatment on the water softener so that the water softener can perform softening treatment on the water in the water softening system.
In the embodiment of the invention, the regeneration treatment mode of the water softener is that a user needs to take out the ion exchange resin, manually prepares salt water with a certain concentration according to the preset setting by using a tool provided by a product, and then puts the ion exchange resin into the salt water to carry out the regeneration treatment of the ion exchange resin, and the treatment is finished within about 30 minutes. The embodiment of the invention can recover the processing capacity of the water softening device for softening water by performing regeneration treatment on the water softening device.
According to the embodiment of the invention, by the control method of the water softening system in the washing machine, the total amount of calcium ions and magnesium ions in water of the water softening system is obtained; obtaining the treatment capacity of the water softener for treating calcium and magnesium ions in water; judging whether the treatment capacity of the water softener for treating calcium and magnesium ions in water is less than the total amount of the calcium and magnesium ions in the water of the water softening system; if the treatment capacity of the water softener for treating calcium and magnesium ions in water is less than the total amount of the calcium and magnesium ions in the water of the water softening system, the water softener is regenerated, so that the water softener can soften the water in the water softening system. Therefore, whether the water softener in the water softening system in the washing machine can continuously perform water softening treatment or not can be judged in time, and when the water softener can not continuously perform water softening treatment, regeneration treatment can be performed in time.
In another embodiment provided by the present invention, in combination with the above embodiment, as shown in fig. 4, the method further includes the following steps:
and step S113, controlling the steam generator to discharge water outwards when the total amount of calcium ions and magnesium ions in the water of the water softening system is larger than the preset total amount.
The total amount of calcium and magnesium ions in the water of the water softening system can be determined according to the above embodiments to control whether the steam generator is drained outwards.
And step S114, controlling the water in the steam generator to enter the water softener to soften the water in the steam generator through the water softener when the total amount of calcium ions and magnesium ions in the water softening system is not more than the preset total amount.
Therefore, the problem that the water softener brings larger water softening treatment burden due to the continuous rising of the concentration of calcium and magnesium ions in the water in the steam generator along with the operation in the steam generator can be avoided. As the water in the water softening system is continuously evaporated, calcium ions and magnesium ions in the water in the steam generator can be left, the concentration of the calcium ions and the concentration of the magnesium ions can be continuously increased, the water in the steam generator is discharged, and a better effect can be achieved.
In addition, the embodiment of the invention can also detect the water level in the steam generator through the water level detector, and control the steam generator to drain water outwards when the water level in the steam generator is greater than the upper limit of the drain water.
In the embodiment of the invention, the total water inflow from the last water drainage to the current water inlet period is calculated by detecting the water level after the steam generator stops working, calculating the difference between the water level and the water inlet level before the steam generator starts working and accumulating all the water level differences after the last water drainage. If the total water inflow reaches the upper limit value of the water drainage, the water drainage pump acts to drain the water in the steam generator so as to prevent water hardness from rising to cause scale formation, otherwise, the water drainage pump does not act, and the total water inflow is continuously accumulated until the total water inflow reaches the upper limit value of the water drainage. Wherein, a drainage pump is arranged at the drainage position of the steam generator.
According to the embodiment of the invention, the water inflow of each time from the last time of regeneration treatment of ion exchange resin to the current time of water inflow is calculated through the calculated difference value between the water level of the steam generator after stopping working and the water level of the water inflow before the steam generator starts working; and then the hardness of each water inflow detected by the hardness detection device 1 is used for calculating the concentration of calcium and magnesium ions of each water inflow, so that the total calcium and magnesium ion treatment capacity is calculated according to each water inflow and the corresponding concentration of calcium and magnesium ions. Comparing the capacity of the ion exchange resin for treating calcium and magnesium ions, and calculating whether the ion exchange resin needs to be regenerated. If the total calcium and magnesium ion treatment capacity is larger than or equal to the allowable calcium and magnesium ion treatment amount of the ion exchange resin, the calculation result indicates that the ion exchange resin needs to be subjected to regeneration treatment, a user is prompted to perform the ion resin regeneration treatment, and meanwhile, the water inlet valve 1 is locked to prevent hard water from entering.
In another embodiment provided by the present invention, with reference to the above embodiment and fig. 1, a first water box (i.e., water box 1) is connected to the water softener, and a first hardness detector (hardness detection device 1) is disposed on the first water box; as shown in fig. 5, the method further includes:
step S211, detecting hardness of water entering the first water box by the first hardness detector.
And step S212, if the hardness of the water entering the first water box is greater than a preset threshold value, the water in the first water box enters a water softener. Or, if the hardness of the water entering the first water box is not more than the preset threshold value, the water in the first water box enters the steam generator.
Illustratively, referring to fig. 1, when a washing process of the washing machine is started, the water inlet valve 1 is opened to start water inlet. Water enters the water box 1, and the hardness detection device 1 in the water box 1 detects the hardness of the inlet water. Wherein the hardness detecting device 1 is an ion selective electrode which generates a potential which varies with the concentration of calcium and magnesium ions in the inlet water, thereby the hardness of water is balanced by the potential of the ion selective electrode.
If the water hardness value corresponding to the potential of the detection result is less than or equal to 10ppm, the requirement is met, the water valve 2 is opened, and water directly enters the steam generator and enters the set water level.
If the water hardness value corresponding to the potential of the detection result is more than or equal to 10ppm, the requirement is not met, the water inlet valve 3 is opened, and water enters the water softener to be softened. The softened water enters the water box 2, and the hardness of the water is detected by the hardness detection device 2 in the water box 2.
In the embodiment of the invention, a flow meter can be arranged at the water inlet end of the water box 1, and the water inlet quantity entering the water box 1 is detected through the flow meter. In addition, the embodiment of the invention can also be provided with a program for automatically regenerating the ion exchange resin. When the ion exchange resin needs to be regenerated, the washing machine automatically disposes the salt solution, starts a regeneration treatment program and automatically performs the regeneration treatment. Therefore, the washing machine is greatly convenient for users to use and is more humanized.
In addition, a second water box (namely, the water box 2) is also arranged between the water softener and the steam generator, and a second hardness detector (a hardness detection device 2) is arranged on the second water box. As shown in fig. 1, in combination with the above embodiments, as shown in fig. 6, the method may further include:
in step S311, the water entering from the first water box is softened by the water softener, and the softened water enters the second water box.
And S312, detecting the hardness of the water in the second water box through the second hardness detector, and if the hardness of the water entering the second water box is greater than a preset threshold value, enabling the water in the second water box to enter the water softener again for softening until the hardness of the water in the second water box is not greater than the preset threshold value.
And step 313, if the hardness of the water in the second water box is not greater than the preset threshold, the water in the second water box enters the steam generator.
