Description
Technical field
The present invention relates to a kind of washing machine, particularly a kind of washing machine and water hardness control method with Hardness Control device.
Background technology
Hard water can reduce the efficient of washing agent, when containing the CATION of divalent calcium ion as the water hardening composition, magnesium ion etc. in the water in laundry, these calcium ions, the surfactant reaction generates the metallicity soap of non-dissolving in magnesium ion and the washing agent, has reduced the surfactant quantity that helps doing washing and has reduced the decontamination ability.The clothes that comes out with hard water looks black dull, slovenly, feels and feels coarse, stiff.Divalent calcium ion, magnesium ion and dust have been combined into insoluble salt, make the difficult removal of spot.And the dirt on the clothing is introduced how stealthy mineral matter in laundry water, makes water quality harder.With the fiber that hard water is washed clothes and also can be spoiled a dress, make the shortening in service life of clothing reach 40%.
For solving the adverse effect of hard water to laundry, a kind of washing machine that the ion exchange resin water softening device is housed arises at the historic moment.Chinese patent 00122234.1 discloses a kind of washing machine that cleans by the adverse effect of removing metal cation.This patent is on the top of washing machine the ion exchange resin water softening device to be housed, and described water softening device mainly is made up of top salt container and bottom ion exchange resin container.The salt container is to be used to produce salt solution, uses for ion exchange resin regeneration.The quantity of the salt that is added in the salt container must be for ion exchange resin regeneration repeatedly, this patent 500g salt of once can packing into.This quantity is exactly can be for regeneration 33 times for ion exchange resin regeneration consumption 15g once.The volume of salt container 32 is made 500ml-550ml, and its inside can hold the dried salt of 500g.
Ion exchange resin is regenerated as follows: salt solution is supplied with electromagnetic valve and is opened, water is stored in the saline container, so the salt dissolving, make salt solution from the water the inside that granular membrane flows into again.Therefore the about salt of the water-soluble 15g that terminates an agreement of injection of 130ml generate concentration and be 10% salt solution.Salt solution flows into ion exchange resin downwards by siphon pipe it is regenerated.The discharge water that contains after the regeneration of a large amount of hardeners is discharged by drainpipe.
The method of the salt solution of this invention generation 10%, be that water is stored in the saline container 31, and the salt container 32 that holds salt also is to be placed in this saline container 31, there is water to exist, salt will constantly dissolve in water, till the saturated concentration that reaches under this temperature, therefore the salt solution of 10% concentration can't guarantee.Be to estimate with access times by the user with salt when in addition, neither science is also inconvenient.Moreover for different regions, even the hardness of water difference is also may be different in the hardness of water from the beginning of areal different time.If, completely all after softening plant is softening, use, also be a kind of waste no matter whether be hard water.The technical scheme how salt solution of relevant 10% concentration guarantees is open in another patent application of applicant.
