Problems solved by technology

The waste water ratio valve in the above-mentioned direct drinking water purifier is in the later stage of use, and the waste water outlet of the waste water ratio valve will be crushed by activated carbon particles, plastic powder on the PP surface, mineral molecules, heavy metal ions, calcium carbonate crystals and other impurities and dirt in the waste water. The microbial colloid is blocked, so that the waste water cannot be discharged from the waste water outlet and the waste water ratio valve is scrapped. Scale will damage the discarded reverse osmosis filter element, the service life of the waste water ratio valve and the reverse osmosis filter element will be reduced, the replacement cycle will be shortened, and the cost will increase

Embodiment 1

[0044] refer to figure 1 As shown, the water treatment system of the present invention includes a water treatment unit 100, the water treatment unit 100 includes a concentrated water port, and the water treatment system also includes a concentrated water discharge branch 200 connected to the concentrated water port, the concentrated water The discharge branch 200 is provided with a control element 300 for controlling the concentrated water discharge ratio, and the water treatment system also includes a cleaning branch 400, and a cleaning unit 410 is provided on the cleaning branch 400, and the cleaning in the cleaning unit 410 Substances can enter the control element 300 through the cleaning branch 400 to dissolve the impurities in the control element 300, so that the impurities on the control element 300 are easily washed away by water, and the control element 300 is not easy to be blocked by impurities. Longer life, longer replacement intervals and lower costs.

[0045] The...

Embodiment 2

[0061] The difference between the second embodiment and the first embodiment is that the cleaning branch 400 is different.

[0062] refer to figure 2 As shown, the cleaning branch 400 is provided with a fluid driving device 430, the fluid driving device 430 can be a pump, for example, the cleaning branch 400 and the reverse osmosis water inlet branch 600 are not connected, the cleaning One end of the branch 400 is not connected to any waterway, the other end of the cleaning branch 400 is connected to the control element 300 , and the cleaning material in the cleaning unit 410 passes through the cleaning branch under the action of the fluid driving device 430 . The path 400 flows to the control element 300 .

Embodiment 3

[0064] The difference between the third embodiment and the first embodiment lies in that the control element 300 is different.

[0065] refer to image 3 As shown, in this embodiment, the control element 300 includes two inlets and one outlet, and the fluid in the cleaning branch 400 enters the control element 300 from one of the inlets and is discharged from the outlet, so The concentrated water in the concentrated water discharge branch 200 enters the control element 300 from the other inlet and is discharged from the outlet. The structure of the control element 300 in this embodiment is different from the control element 300 in Embodiment 1, but both the control element 300 in this embodiment and the control element 300 in Embodiment 1 can control the discharge ratio of concentrated water.

Abstract

The invention discloses a water treatment system, a water purifier and a control method of a water treatment system. The water treatment system includes a water treatment unit, and the water treatmentunit includes a concentrated water port, the water treatment system also includes a concentrated water discharge branch connected to the concentrated water port, the concentrated water discharge branch is equipped with a control element for controlling the concentrated water discharge proportion, the water treatment system also includes a cleaning branch, the cleaning branch is equipped with a cleaning unit, and the cleaning substance in the cleaning unit can enter the control element through the cleaning branch so as to realize dissolution of impurities in the control element. According to the water treatment system and the water purifier provided by the invention, the cleaning substance in the cleaning unit can enter the control element through the cleaning branch so as to dissolve impurities on the control element, so that impurities on the control element can be easily washed away by water, the control element is not easily blocked by impurities, the service life is increased, thereplacement cycle is prolonged and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a water treatment system, a water purifier and a control method for the water treatment system. Background technique [0002] At present, with people's awareness of drinking water health, water purifiers are more and more recognized by everyone. The direct drinking water purifier of the prior art includes PP cotton, activated carbon pre-filter and reverse osmosis filter. After the raw water passes through the reverse osmosis membrane filter, pure water and waste water will be produced, and the waste water will pass through the waste water outlet of the waste water ratio valve. discharge. The waste water ratio valve in the above-mentioned direct drinking water purifier is in the later stage of use, and the waste water outlet of the waste water ratio valve will be crushed by activated carbon particles, plastic powder on the PP surface, mineral molecules, heavy metal ions, ...
