The working mode of the water softener comprises a vacation mode and a normal mode, a user can select the corresponding working mode of the water softener according to the living state, if the user has long-time home departure requirement, the working mode of the water softener can be set, the vacation mode is started, at the moment, the working mode is judged to be the vacation mode, the water softener can work in various settings of the vacation mode, the regeneration time of the ion exchange resin is calculated at regular time, and the resin regeneration is controlled. When the user does not need to go out and does not start the holiday mode of the water softener, the working mode is judged to be not the holiday mode, the water softener works in various settings of the normal mode, the regeneration time of the ion exchange resin is quantitatively calculated according to the set threshold value of the water yield, and the resin regeneration is controlled. According to the demands of different stages of users, the water softener adopts different working modes to continuously work in a stable state, so that the machine loss caused by improper use can be reduced, and the service life of the water softener is prolonged.
S230, controlling the water softener to work according to the vacation mode.
When the operation mode of the water softener is determined to be the holiday mode, the water softener will remain in operation with various settings of the holiday mode. Specifically, fig. 3 is a schematic flow chart of a control method of a water softener in a vacation mode according to an embodiment of the present invention, and as can be seen from the figure, the method specifically includes:

S232, setting the preset duration b of the water softener, setting the initial raw water hardness c to 0 and setting the time recording parameter d to 0.
S233, flushing the resin, and measuring the hardness e of the raw water after the time b.
S234, accumulating the raw water hardness values for each preset period of time, c=c+e.
S235, judging whether the system reaches the set holiday days, and judging whether d is larger than a.
S236, determining the hardness value of raw water of the water softener according to the accumulated raw water hardness value c of each time period, the holiday days a and the preset duration b of the water softener, and updating the hardness value of the raw water to be c/(a/b) by the system.

In the steps S232-S234, the preset duration b of the water softener is used for cleaning the ion exchange resin at fixed time, the system can wash the resin at the default time, bacterial breeding is reduced, and caking of filter materials is avoided due to long-time immobility; the method comprises the steps that the initial raw water hardness of the water softener is 0, the raw water hardness of the water softener is not detected by a default system, a time recording parameter d is the accumulation of time after the opening of a holiday mode, the ion exchange resin is washed every time the time recording parameter d is accumulated to be integral multiple of the preset duration of the water softener, one side of the raw water hardness is detected after the ion exchange resin is washed once, and the hardness e is accumulated once. For example, if the preset time period is set to 0.5 day, the ion exchange resin is washed once every time the time recording parameter reaches an integer multiple of 0.5 day, and the raw water hardness is detected on one side, and the raw water hardness detection value is accumulated once.
In the steps S235-S236, judging whether the working time of the water softener reaches the set holiday days or not by using the time recording parameters, if the working time does not reach the set holiday days, repeatedly executing the step S233 by the water softener, and if the working time reaches the set holiday days, processing the hardness value of the raw water of the water softener according to the accumulated raw water hardness value c of each time period, the holiday days a and the preset duration b of the water softener and updating the raw water hardness value of the system. For example, if the number of holidays a is 5, the preset duration b of the water softener is 0.5 day, and the hardness value c of raw water in each accumulated time period is X, then the hardness value of raw water needed to be updated by the water softener after reaching the set holiday is X/(5/0.5).

S240, controlling the water softener to work according to a normal mode.
When the operation mode of the water softener is determined to be the normal mode, the water softener keeps running with various settings of the normal mode, and specifically, fig. 4 is a schematic flow chart of a water softener control method in the normal mode according to an embodiment of the present invention, and as can be seen from the figure, the method specifically includes:
s241, setting a designated water production amount i of the water softener.
S242, setting the preset water production amount j of the water softener, setting the initial raw water hardness k to 0 and setting the water flow recording parameter m to 0.
S243, when the water flow reaches integer times of the preset water production amount j, measuring the hardness n of the raw water of the water softener.
S244, accumulating the raw water hardness values at each preset water production stage, wherein k=k+n.
S245, judging whether the system water flow reaches the designated water production amount or not, and judging whether m is larger than i or not.

S247, updating the raw water hardness of the water softener, changing the periodic water yield, determining the resin regeneration time according to the updated hardness value, and controlling the regeneration of the ion exchange resin according to the regeneration time.
In step S241, the water softener specific water production amount i may be set according to the usage specification of the water softener and the daily water consumption condition of the user, for example, may be 20l,100l,500l, etc., which is not limited in the embodiment of the present invention.
In the steps S242 to S244, the preset water production amount j of the water softener is used for quantitatively detecting the change condition of the raw water hardness of the water softener, the initial raw water hardness of the water softener is 0, the default system does not detect the raw water hardness of the water softener, the water flow recording parameter m is the accumulation of the water flow after the water softener is started from the normal mode, and whenever the water flow recording parameter m is accumulated to an integral multiple of the preset duration of the water softener, one side of the raw water hardness is detected, and the primary hardness n is accumulated. For example, if the designated water production amount is set to 100L and the preset water production amount j is set to 10L, when the over-water flow recording parameter m reaches an integral multiple of 10L, one-side detection is performed on the raw water hardness, and the raw water hardness detection value is accumulated once.
In the steps S245-S246, it is determined whether the water softener achieves the set designated water production amount by using the water flow recording parameter, if the water softener does not achieve the set designated water production amount, the step S243 is repeatedly executed, if the water softener achieves the set designated water production amount, the hardness value of the raw water of the water softener is processed and updated according to the accumulated raw water hardness value k at each preset water production amount stage, the designated water production amount i and the preset water production amount j of the set water softener, and the hardness value of the raw water of the system is exemplified by that if the designated water production amount is 100L, the preset water production amount j of the set water softener is 10L, and the accumulated raw water hardness value k at each preset water production amount stage is Y, then the hardness value of the raw water required to be updated by the water softener after achieving the set designated water production amount is Y/(100/10).
In the step S247, according to the hardness value of the raw water of the water softener obtained in the step S246, the periodic water yield of the water softener is obtained according to the relation between the effective resin filling amount and the resin work exchange capacity, and the specific calculation relation is as follows: cycle water yield = effective resin fill amount resin work exchange capacity/raw water hardness, then according to the relationship of cycle water yield and rated water yield: regeneration time = cycle water yield/rated water yield, the regeneration time of the ion exchange resin is determined, and then the regeneration of the resin is controlled according to the regeneration time of the resin, and the regeneration time of the ion exchange resin is 10h, and then the soft water can control the ion exchange resin to carry out salt adding reverse reaction when the ion exchange resin reaches 10h, so that calcium and magnesium ions adsorbed on the resin are removed, and the ion exchange resin is regenerated.
In a specific embodiment, the water softener comprises a salt tank, wherein the salt tank is used for storing regenerated salt required for regenerating the ion exchange resin, a salt position detection device is arranged in the salt tank, and the salt position detection device can detect the residual salt amount of the salt tank by starting a signal lamp to emit infrared signals. The salt level detection device can detect the residual salt amount of regenerated salt according to a preset period, such as 4 hours, 8 hours and the like, namely the salt level detection device detects the salt amount of the salt tank once every preset period, and through intermittent detection, the working time of the salt level detection device is reduced, and the service life of the salt level detection device is prolonged.
In the prior art scheme, salt position detection device sets up in salt tank bottom, mainly detects salt position through salt position detection device that salt tank bottom set up, when salt position detection device sensed salt volume in the salt tank insufficient, the machine can take place the warning sound, reminds the user to add salt, this can lead to the user to discover when salt tank salt volume is too low, if there is not salt volume storage in the family, can not in time add salt to the water softener, the water softener will constantly report to the police, moreover because salt position detection device needs incessantly to detect salt position, can lead to salt position detection device fragile, influence the holistic result of use of water softener.
