Description
Technical Field
The invention relates to the technical field of water purification equipment, in particular to a waterway system and water purification equipment.
Background
The theory of dissolution-diffusion considers that the RO membrane is a non-porous complete membrane, solutes such as water molecules and salts can be dissolved in the membrane, and the water molecules and solute molecules dissolved in the membrane can diffuse to the other side of the RO membrane under the action of external pressure, but the diffusion speeds are different. When water is normally produced, the diffusion speed of water molecules under the external pressure is far higher than that of solute molecules, so that the water molecules can rapidly permeate the RO membrane, most of the solute molecules can be enriched on the raw water side, and the separation of the solute molecules and the water molecules is realized.
However, when the water purifier is stopped and left standing for a long time, the concentration of solute molecules on the raw water side is much higher than that on the pure water side, solute diffusion occurs under the drive of the concentration gradient, and the solute molecules gradually permeate the RO membrane and finally reach the diffusion equilibrium. This results in an increase in the pure water side water TDS (Total dissolved solids, also known as Total dissolved solids, measured in milligrams per liter (mg/L), which indicates how many milligrams of dissolved solids are dissolved in 1 liter of water. Therefore, when the water purifier produces water again, the first cup of water that the user received is the water of the high TDS value that flows out from the RO membrane element promptly, and quality of water can't satisfy the demands.

As shown in fig. 1, when the waterway system is in a water production state, the tap 700 is turned on, and pure water generated by the pure water waterway 10 flows out from the tap 700, under normal conditions, the tap 700 will flow out pure water with a low TDS value, but when the waterway system is left for a long time, the tap 700 will flow out pure water with a high TDS value;
as shown in fig. 2, when the waterway system is in the water storage state, the tap 700 is turned off, and the pure water generated by the pure water waterway 10 flows into the water storage container 20, and the pure water flowing into the water storage container 20 is pure water with a low TDS value because the pure water enters the water storage state after the water production state is completed, i.e., the tap 700 is turned off;
as shown in fig. 3, when the water path system is in the flushing state, the water tap 700 is turned off, and the pure water with a low TDS value in the water storage tank 20 flows to the water inlet 610 of the reverse osmosis filter device, so as to flush the reverse osmosis filter device, the waste water is discharged from the waste water outlet 630 of the reverse osmosis filter device, and the waste water is discharged through the water outlet of the water path 40, and the pure water with a high TDS value after flushing the reverse osmosis filter device is discharged from the pure water outlet 620 of the reverse osmosis filter device, and the pure water with a high TDS value flows into the water path 40 through the connecting water path 50, and is finally discharged through the water outlet of the water.
