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 that flows out from the RO membrane element promptly, and quality of water can't satisfy the demands.

Specifically, when the faucet 600 is in the open state, the first water inlet solenoid valve 100 is open, the second water inlet solenoid valve 200 is open, and the third water inlet solenoid valve is closed, the waterway system is in the second water outlet state, and at this time, the faucet 600 flows out pure water with a low TDS value.
Further, as shown in fig. 3 to 5, in order to enable the faucet 600 to simultaneously flow out the pure water with a low TDS value when the waterway system is in the first water outlet state, in an embodiment of the present application, the waterway system further includes a pressure water storage container, and the pressure water storage container is connected to the water outlet side of the pure water waterway 10.
So, after the user water receiving finishes, tap 600 closes, and water purification water route 10 can continue system water and store the pure water of the low TDS value that makes to pressure water storage container this moment, and after pressure water storage container reached predetermined water level height, water purification water route 10 stopped system water, so, the pure water of the low TDS value of deposit can use when next opening tap 600 in the pressure water storage container. So, when opening tap 600 next time, the raw water that first intake end got into when rinsing reverse osmosis filter equipment, the pure water of the low TDS value of storing can follow tap 600 outflow in the pressure water storage container, therefore the user need not wait for and can obtain the pure water of low TDS value.
It should be noted that the preset water level of the pressure water storage container can be determined according to the required flushing water amount of the reverse osmosis filtering device, specifically, for a high-flux water purifier, taking a water purifier with 400G flux as an example (G, gallon, which means gallon, is a volume unit, and 1 gallon is about 3.79 liters)) "first cup water" TDS test, it is found that pure water with higher TDS value is mainly concentrated in 1 st, 2 nd, 3 th and 4 th cups (200 ml water each time), and the total amount of pure water with higher TDS value is about 800ml, therefore, the preset water level of the pressure water storage container is generally larger than or equal to 800ml, and correspondingly, the volume of the pressure water storage container is 1L to 2L.
Further, a description will now be given of a waterway system having a pressurized water storage container. The pressure water storage container has a water inlet state (shown in fig. 5) and a water outlet state (shown in fig. 3), when the water tap 600 is in a closed state, the control module controls the first water inlet electromagnetic valve 100 to be opened, controls the second water inlet electromagnetic valve 200 to be opened, and controls the third water inlet electromagnetic valve 300 to be closed, so that pure water with a low TDS value flows into the pressure water storage container, and the pressure water storage container is in a water inlet state; when waterway system is in first play water state, tap 600 is in the open mode, control module control first solenoid valve 100 of intaking is opened, is controlled second solenoid valve 200 of intaking is closed to predetermine for a long time, control third solenoid valve 300 of intaking is opened and is predetermine for a long time, the pure water warp of the low TDS value in the pressure water storage container play tap 600 flows, and pressure water storage container is in a water state.
Further, with continued reference to fig. 3 and fig. 5, a structure of the pressure water storage container will now be described, the pressure water storage container includes a pressure tank 40 and a pressure switch 50, an opening communicating with the purified water path 10 is formed on the pressure tank 40, and the pressure switch 50 is used for controlling to open or close the opening.
Specifically, the pressure switch 50 is a high-pressure switch, the pressure switch 50 is a normally closed switch, and when the pressure switch 50 is closed, the opening is communicated with the purified water channel 10, and at this time, the purified water with a low TDS value can flow into the pressure tank 40; when the water level in the pressure tank 40 reaches the preset water level, the pressure switch 50 is turned off, and the opening is disconnected from the purified water path 10, and at this time, the pure water with a low TDS value cannot flow into the pressure tank 40.
