Drainage structure, water purifier and drainage method

Abstract

The invention provides a drainage structure, a water purifier and a drainage method. The drainage structure comprises a high pressure pump, a reverse osmosis filter element and a first electromagneticvalve; a water inlet of the high pressure pump is communicated with the first electromagnetic valve; a second total dissolved solid detection device is arranged on a purified water outlet of the reverse osmosis filter element; the purified water outlet of the reverse osmosis filter element is communicated with a wastewater opening through a fourth electromagnetic valve; a water outlet of the first electromagnetic valve is communicated with a second electromagnetic valve, a water outlet of the second electromagnetic valve is communicated with an inlet of a water storage tank, and a water outlet of the water storage tank is communicated with a purified water faucet; and the purified water outlet of the reverse osmosis filter element is communicated with the water outlet of the water storagetank through a third electromagnetic valve. Due to the drainage structure, the total dissolved solid in a first cup of water is reduced, the drinking water is healthier, and the water yield of the water purifier is increased within a short period of time.

Description

technical field [0001] The present invention relates to a structure for a water purifier, a water purifier using the structure and a method for using the structure. 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 water by using the selective permeability of selective membranes that can only pass through water but not solutes. The reverse osmosis water purifier is a water purifier that mainly uses the principle of reverse osmosis for water treatment. Reverse osmosis water purifier (RO machine) is a kind of household drinking water equipment that appears on the market, but its appearance has been well received by more and more consumers, especially favored by water machine users, because it eliminates the need to buy barrels The cost of filling water and the cumbersomeness of transporting bottled water. [0003] Due to the easy breeding of bacte...

Problems solved by technology

[0003] Due to the easy breeding of bacteria in the pressure barrel of the barrel-type reverse osmosis water purifier, it was gradually replaced by the barrel-less reverse osmosis water purifier; this caused the calcium and magnesium ions on the concentrated water side of the reverse osmosis membrane to slowly Penetrates into the clean water side; resulti
