Embodiment 1

[0044] Embodiment one: see figure 1 . A mechanical double faucet is added to the waste water return system, the pure water outlet end of the first reverse osmosis filter element 11a is connected to the drinking water end of the double faucet, and the second one-way valve 15b and the first high pressure switch 16a are sequentially added to the pipeline; A reverse osmosis filter element 11a is divided into two waste water outlets, one of which is directly connected to the domestic water end of the double faucet, and a third one-way valve 15c and a second high-pressure switch 16b are sequentially added to the pipeline; the other is a waste water return pipeline, and the waste water It can be returned to before the booster pump 12 through the first flow limiting valve 14a, and there is a branch on the waste water return line which is the first waste water direct discharge line Q1, which is used for waste water direct discharge when necessary. There is a first TDS probe 19a at the...

Embodiment 2

[0049] Embodiment two: see figure 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 front outlet water flow rate is less than 8L / min. The first TDS probe 19a is before the waste water return pipeline, before the pre-filter element 17a or after the pre-filter element 17a.

[0050] The user turns on the drinking water faucet: the first high-pressure switch 16a detects a pressure change, starts the booster pump 12, and starts water production; the tap water is coarsely filtered by the pre-filter 17a and flows into the first reverse osmosis filter 11a, and is divided into one path of pure water and one path Wastewater and pure water are discharged from the drinking water faucet for drinking, and the waste water flows bac...

Embodiment 3

[0054] Embodiment three: see image 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. The second TDS probe 19b is behind the first reverse osmosis filter element 11a, before or after the rear filter element 17b, the first high pressure switch 16a or the second one-way valve 15b.

[0055] The user turns on the drinking water faucet: the first high-pressure switch 16a detects a pressure change, starts the booster pump 12, and starts water production; after the tap water flows into the first reverse osmosis filter element 11a, it is divided into one path of pure water and one path of waste water, and the pure water passes through the rear filter element After 17b, it is discharged from the drinking water faucet for drinking, and the w...

Abstract

The invention discloses a water purifier with double TDS probes. Waste water flows back to the front of a first reverse osmosis filter element through a pipeline, is mixed with tap water and then enters the first 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 first reverse osmosis filter element are ensured; meanwhile, wastewater is connected with an original tap water faucet of a household kitchen of a user, wastewater discharge is completed when the tap water faucet is opened, wastewater is reutilized, and the requirement for ecological environmental protection is met. In addition, a TDS probe and a waste water direct discharge pipeline are further added, and waste water can be directly discharged when it is detected that the desalinization rate of pure water outlet water is not qualified.

Description

technical field [0001] The invention relates to the technical field of water purifiers, in particular to a water purifier with double TDS probes. Background technique [0002] Through the process of reverse osmosis, it is possible to move water from a more concentrated solution to a less concentrated solution. Since inorganic ions, colloidal substances and macromolecular solutes cannot pass through the reverse osmosis filter element, in this process, unnecessary substances are left 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 the osmotic pressure increa...
