Background

The water softener mainly removes calcium and magnesium ions in water through ion exchange resin to reduce the hardness of water. Compared with tap water, the soft water has very obvious taste and hand feeling. After the soft water is used, scales are not generated in the water cup, the teapot, the bathtub and the water bucket, and the water cup, the teapot, the bathtub and the water bucket are easier to clean. The water pipe in the house can not scale, the service life of the water heater is longer, and the hot water flow is smaller and smaller because of long service time. The soft water can reduce the use amount of detergent, soap and other washing articles, greatly reduce the maintenance cost of water pipes, prolong the service life of clothes by 32% compared with the service life of clothes washed in hard water, prevent clothes from becoming full of spring, make white shirts whiter, make blue shirts bluer and make the clothes brighter.

The main filter material of the existing water softener is softening resin which is used for adsorbing calcium and magnesium ions in water. When the exchange capacity of the softening resin is saturated, 5-8% of saline water is needed to carry out backwashing on the softening resin, calcium and magnesium ions adsorbed on the resin are exchanged by sodium ions, and the calcium and magnesium ions can be exchanged again by the softening resin to soften the water quality. The existing water softener uses saturated brine in the backwashing flow, so that the concentration of the brine is high, the salt consumption is high, and the environment is easily subjected to large burden.

In addition, the existing water softeners are designed by a single resin barrel, if a large flow is needed, a large barrel body is inevitably needed, the whole volume of the water softener is large, the actual resin volume is small, the required saline volume is generally 2-3 times of the resin volume during backwashing, a very large saline bin (tank) needs to be matched, the volume of the water softener is increased continuously, the cost is increased, the water softener cannot be popularized, equipment cannot be placed into a cabinet after the volume is increased, and the water softener is difficult to install after finishing.

As an embodiment of the present invention:

a normal washing state: after entering from the water inlet valve 10, water firstly passes through the flow meter 19, the flow meter 19 carries out accumulation counting, then the water flows into the water path switching assembly, passes through the normally open electromagnetic valve 18 to the water inlet cavity 205 in the flow dividing and converging assembly 20, is evenly distributed to the resin filtering bin 3, is guided into the bottom of the resin filtering bin 3, flows through the resin from bottom to top to seep out, completes the exchange of calcium and magnesium ions, completes the converging at the permeable cavity 204, finally passes through the reversing valve 11, and flows out at the soft water port 12 for users to use.

While the numbers at the display panel are now counted down by 99.9%, the numbers gradually decrease with user usage.

And (3) backwashing state: when the flow meter 19 has accumulated to a set value or set time, the apparatus will enter the backwash state at 1 point in the next morning.

Before the resin is backwashed, the water level of the salt storage bin 6 is always kept at the lowest water level second water level sensor 7, at the moment, softened salt is not completely immersed, only a small part of softened salt is soaked in water, and the salt water in the bin is in a saturated state. After the device is started and reversely cleaned, the normally open electromagnetic valve 18 is closed, the normally closed electromagnetic valve 16 is opened, water is injected into the salt storage bin 6 until the water level reaches the position of the first water level sensor 5, the normally open electromagnetic valve 18 is opened, the normally closed electromagnetic valve 16 is closed, water feeding is stopped, and the concentration of mixed salt water is reduced;
