Embodiment 1

[0065] Embodiment 1: Please refer to 1. A mechanical double faucet is added to the waste water return system, a second one-way valve 15b is set between the first water outlet 112 and the first high pressure switch 16a, and a second check valve 15b is set between the first waste water port 113 and the second high pressure switch 16b. Three check valves 15c.

[0066] The first flow-limiting valve 14a on the first branch P1 is a valve body with a flow-limiting effect. Combination of one-way valve and high-pressure switch to avoid frequent start-up: Due to the existence of the one-way valve, when the drinking water faucet is closed, the water is limited between the one-way valve and the faucet, the water pressure remains stable, and the high-pressure switch receives a stable pressure signal , remain disconnected.

[0067] The user opens the drinking water faucet (the drinking water inlet 131 is connected to the drain outlet 133): the first high pressure switch 16a detects a pres...

Embodiment 2

[0069] Embodiment 2: Please refer to 2. In this embodiment, on the basis of Embodiment 1, a pre-filter 17a is added at the front end of the booster pump 12. The type of the pre-filter 17a can be different forms of PP, different forms of activated carbon, ultrafiltration, nanofiltration and the above materials Composite filter elements, etc., the water outlet flow rate of the pre-filter element 17a is <8L / min.

[0070] The user opens the drinking water faucet (drinking water inlet 131 is connected to the outlet 133): the first high pressure switch 16a detects a pressure change, starts the booster pump 12, and starts water production; After a reverse osmosis filter element 11a, it is divided into one path of pure water and one path of waste water. The pure water is discharged from the drinking water faucet for drinking, and the waste water flows back to the booster pump 12 through the first flow limiting valve 14a. A reverse osmosis filter element 11a filters again to realize z...

Embodiment 3

[0072] Embodiment 3: Please refer to 3. In this embodiment, on the basis of Embodiment 1, a rear filter element 17b is added to the pure water outlet pipe of the first reverse osmosis filter element 11a, before the second check valve 15b and the first high pressure switch 16a. The species can be activated carbon in different forms.

[0073]The user opens the drinking water faucet (the drinking water inlet 131 is connected to the drain outlet 133): the first high pressure switch 16a detects a pressure change, starts the booster pump 12, and starts water production; after tap water flows into the first reverse osmosis filter element 11a, the One path of pure water and one path of waste water. The pure water passes through the rear filter element 17b and is discharged from the drinking water faucet for drinking. The waste water flows back to the booster pump 12 through the first flow limiting valve 14a and mixes with tap water before entering the first reverse osmosis filter elem...

Abstract

The invention discloses a waterway system and a water purifier, in the waterway system, wastewater flows back to a reverse osmosis filter element through a pipeline, is mixed with tap water, and then enters the reverse osmosis filter element again for secondary filtration. According to the method, the discharge of wastewater can be greatly reduced while the performance and the service life of the reverse osmosis filter element are ensured; meanwhile, wastewater is connected with the domestic water outlet assembly, wastewater discharge is completed when the domestic water outlet assembly is opened, wastewater is reutilized at the same time, and the requirement for ecological environmental protection is met.

Description

technical field [0001] The invention relates to the technical field of water purifiers, in particular to a waterway system and a water purifier provided with the waterway system. Background technique [0002] Through the process of reverse osmosis, it is possible to move water from a more concentrated solution to a less concentrated one. Since inorganic ions, colloidal substances and macromolecular solutes cannot pass through the reverse osmosis filter element, in this process, unnecessary substances remain at the end of the solution with high concentration, and purified pure water is obtained at the end with low concentration. The working process of the reverse osmosis filter element, the core component of the water purifier, is actually a process of liquid concentration. The salt content in the water increases continuously as the water flows through the surface of the reverse osmosis filter element, and the osmotic pressure of the water also increases continuously. When t...
