Direct drinking machine

Abstract

The invention relates to an instant drinking machine which can supply the direct drinking water. The technical proposal is to make one part of the pure water enter the washing tank. When the pure water pressure in the barrel reaches the given value, the high pressure switch opens to make the pure water in the washing tank flow from the reverse osmosis membrane waste water gap into the reverse osmosis membrane and flush the reverse osmosis membrane, permute the residual water in the reverse osmosis membrane using the pure water, and escort the waste water to the raw water preposition processing device by the booster pump action, which makes the TDS value the same at the pure water side and the raw water side in the reverse osmosis membrane, and ensures the first cup of water having the desalinization ratio higher than 80% when turning the cock and becomes a real instant drinking machine.

Description

technical field [0001] The invention relates to a pure water machine, in particular to a direct drinking machine which can really directly drink water. Background technique [0002] There are many kinds of pure water machines on the market, but none of them can solve the TDS CLIP phenomenon. The solvent of the solution penetrates into the high-concentration solution, and the permeation process stops when the concentrations on both sides are the same. The working principle of the reverse osmosis membrane is to increase the pressure on one side of the high-concentration solution. At this time, the solvent in the high-concentration solution permeates into the low-concentration solution. The concentration of low-concentration solution is getting lower and lower to become pure water, and the concentration of high-concentration solution is getting higher and higher to become waste water. When the pure water machine is working normally, it produces pure water for drinking. When it ...

Problems solved by technology

) At this time, if you turn on the pure water machine to drink pure water, the first glass of water contains too much total soluble solids, which is harmful to the human body

At the same time, the water production speed of the reverse osmosis membrane of the original direct drinking machine sold on the market is slow, generally 130ml / min, and the pressure tank must be added to ensure the water production speed, the structure is heavy, the cost is high, the installation space increases, and the pressure tank takes a long time Bacteria will grow inside, causing safety hazards
