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

Embodiment 1

[0064] The water supply device of the washing machine has a softener 1 and a regeneration fluid switch valve 3 connected through a hose 904. The regeneration fluid switch valve is installed under the regeneration agent dispenser 2. The pipe 901 is connected with a water inlet solenoid valve 5; the regenerant dispenser 2 is composed of a regenerated liquid container 22 and a built-in regenerated agent holding box 21, and the regenerated liquid container 22 is provided with a water inlet 201 on one side and an overflow on the other side The mouth 202 is located at the water inlet 201. An outlet of the water inlet solenoid valve 5 is connected to the water inlet 101 of the softener 1 through a hose 902; the water outlet 152 of the softener is connected to the electrolytic cell 4 through a hose 905; The control circuit board of the microprocessor CPU controls the water supply program;

[0065] The softener 1 has a shell 12, the inner sleeve of which is equipped with an ion exchang...

Embodiment 2

[0161] The difference from Embodiment 1 is that the water supply device of the washing machine is connected with a three-way switching valve 6 through a hose 902 between the softening water outlet 502 of the solenoid valve 5 and the softener 1, and a water outlet 602 of the three-way switching valve is passed through The hose 908 is connected to the water inlet 101 of the softener 1, and the other water outlet 603 is connected to the water outlet chamber 104 of the softener; when the circuit system detects that the tap water hardness is low enough, it does not need to be softened, and can also meet the requirements of electrolysis and washing. Requirements, in this case, through the control of the circuit board circuit, the solenoid valve 5 and the three-way switching valve 6 are powered on, and the tap water passes through the solenoid valve 5 from the water outlet 603 of the three-way switching valve to directly enter the water outlet chamber 104 of the softener 1 to supply wa...

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 ...
