Water feeding device for washing machine

Abstract

The invention relates to a washing machine feeding apparatus which has the advantages of capability of softening hard water and electrolyzing soft water and then improving washing effect, capability of prolonging service life of an electrolysis unit, and non-necessity of throwing regenerants into a mollifier each time. The invention comprises a water inlet solenoid valve (5), and a regenerant dispenser (2) and the mollifier (1) which are respectively connected with a water outlet for regeneration (501) and a water outlet for softening (502) of the solenoid valve through pipes, and a control circuit board which is provided with a microprocessor CPU is arranged, wherein, an overfall gap (202) is arranged on the side face of a regenerant container (22) of the regenerant dispenser; a regenerant switch valve (3) is arranged at the bottom of the regenerant container (22); an outlet (302) of the regenerant switch valve is connected with a regenerant inlet (153) of the mollifier through a pipe; a water outlet (152) of the mollifier is connected with an electrolysis bath (4) through a pipe. The invention is suitable for being taken as a washing machine feeding apparatus.

Description

technical field [0001] The invention relates to a washing water treatment device, in particular to a washing machine water supply device. Background technique [0002] 1. Due to the different ways of water intake and treatment in various places, the supplied tap water contains divalent cations of calcium ions and magnesium ions as hardness components to varying degrees. These ions react with the surfactant in the washing process, resulting in insoluble Metallic soap bases in water reduce the amount of surfactant required for washing, resulting in lower detergency. In addition, the metal soap base produced will leave white spots on the clothes when rinsing is insufficient, which is also the cause of yellowing and odor; moreover, when it adheres to the outer wall of the washing tub and accumulates, there will be mold, etc. reproduce. [0003] These unfavorable effects are particularly notable when soap is used as a detergent, and in areas with high water hardness, it is not ...

AI Technical Summary

Problems solved by technology

[0008] 1) Due to air bubbles, pipelines, etc., there may be incomplete siphon discharge of brine

Once this happens, there will be water remaining in the regeneration box. When the dissolved water is regenerated for the second time, it is originally hoped that the water will enter the siphon port. Due to the residual water in the front, it will exceed the siphon port. not enough time to dissolve

The regeneration function of the softener is seriously affected

It may even be difficult to return to the designed regenerative state, rendering the softener useless for softening

[0009] 2) After the resin is regenerated with salt water, there will be salt residues in the resin. If these salts enter the washing bucket directly with the water inlet action without dilution (cleaning), it may cause damage to the metal parts in the pipeline and bucket. rust

[0012] However, if the hardness of the raw water that actually enters the softening device is only 100PPm and is also regenerated according to the standard of regenerating 100L of water once, 75% of the exchange capacity will be wasted
