Embodiment 1

[0057] figure 2 It is a schematic diagram of the block structure of the water purifier provided in Embodiment 1 of the present invention.

[0058] Among them, the water purifier provided in this embodiment achieves the purpose of reducing the TDS value while achieving a high recovery rate, so that the service life of the reverse osmosis membrane is not easily reduced rapidly and the combined flushing solenoid valve is not easy to scale.

[0059] Among them, in this embodiment, such as figure 2 As shown, the water purifier includes: a first filter unit 10, a reverse osmosis membrane device 50, a pressurization device 40 and a combined flushing solenoid valve 71, wherein the booster device 40 is located between the first filter unit 10 and the reverse osmosis membrane device 50 On the connected pipeline, the combination flushing solenoid valve 71 is arranged on the discharge pipe 70 connected to the concentrated water outlet of the reverse osmosis membrane device 50, and the ...

Embodiment 2

[0075] image 3 It is a schematic diagram of the block structure of the water purifier provided in Embodiment 2 of the present invention, wherein, the difference between this embodiment and the above-mentioned embodiment is: in this embodiment, such as image 3 As shown, it also includes: a waste water proportioner 82 (also known as waste water ratio), the water inlet end of the waste water proportioner 82 communicates with the discharge pipe 70 between the reverse osmosis membrane device 50 and the second filter unit 20, that is, the waste water proportion The water inlet end of the device 82 is connected with the concentrated water outlet of the reverse osmosis membrane device 50, and the water outlet end of the waste water proportional device 82 is connected with the return pipe 80 between the backflow control valve 81 and the pressurizing device 40, that is, the waste water ratio The water outlet end of the device 82 is connected with the water inlet end of the pressurizat...

Embodiment 3

[0078] Figure 4 It is a schematic flow chart of the water purification method of the water purifier provided in Embodiment 3 of the present invention. In this embodiment, the water purifier described in any of the above embodiments is used for water purification, specifically as Figure 4 and figure 2 Shown, water purification method comprises the steps:

[0079] Step 301, when the water pressure in the water inlet pipeline of the water purifier reaches the preset pressure value, start the booster device of the water purifier and the control valve on the water inlet pipeline, and close the combined flushing solenoid valve and return pipe of the water purifier On the control valve, so that the water purifier enters the water purification mode.

[0080] Wherein, in this embodiment, when the water purifier starts purifying water, when the pressure in the water inlet pipeline reaches the preset pressure value, specifically, when the pressure in the water inlet pipeline reaches...

Abstract

The invention provides a water purification machine and a water purification method thereof. The water purification machine comprises a first filter unit (10), a reverse osmosis membrane device (50),a pressurization system (40), a combined washing electromagnetic valve (71) and a second filter unit (20); the second filter unit (20) is arranged on a drainage pipe (70); the water inlet end of the second filter unit (20) is communicated with a concentrated water outlet of the reverse osmosis membrane device (50); and the water outlet end of the second filter unit (20) is communicated with the water inlet end of the combined washing electromagnetic valve (71) and a reflux pipe (80). The water purification machine provided by the invention solves the technical problem that when the existing water purification machine is high in recovery ratio, a TDS value in concentrated water is high, so that the service life of a reverse osmosis membrane is rapidly shortened, and the combined washing electromagnetic valve is liable in scaling.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a water purifier and a water purifying method thereof. Background technique [0002] Reverse osmosis is a process that uses a pressure higher than the osmotic pressure as the driving force to separate water molecules from solutes from the water body by using the selective permeability of the selective membrane that can only pass through water but not solutes. The osmotic water purifier is a machine that mainly uses the principle of reverse osmosis for water treatment. The working principle is to apply a certain pressure on the water, so that the water molecules and ionic mineral elements pass through the reverse osmosis membrane, and most of the inorganic substances dissolved in the water Salt (including heavy metals), organic matter, bacteria, and viruses cannot pass through the reverse osmosis membrane, so that the permeated pure water and the impermeable concentrated water ...
