Double-water-outlet-waterway system of water purifier and water purifier

Abstract

The invention discloses a double-water-outlet waterway system of a water purifier. The system comprises a water inlet pipe, a pretreatment module and an RO (Reverse Osmosis) treatment module which are connected in sequence; a water inlet electromagnetic valve and a booster pump are arranged between the pretreatment module and the RO treatment module; and a pure water cavity and a water purification cavity of the RO treatment module are respectively connected with a pure water pipeline and a wastewater pipeline. The system is characterized in that the water purification cavity of the RO reverse osmosis treatment module is also connected with a water purification pipeline for outputting purified water; and when purified water is used, the booster pump is started, and the purified water treated by the pretreatment module flows through the surface of the reverse osmosis membrane of the RO treatment module and enters the water purification pipeline. The water outlet flow of purified water is increased through the pressurization effect of the booster pump, and the water flow requirement of a user for washing water is greatly met; and meanwhile, high-speed purified water flows through the surface of the RO membrane to wash dirt and impurities on the surface of the membrane at a high speed, so that the service life of the RO membrane is prolonged.

Description

technical field [0001] The invention relates to the technical field of water purifier equipment, in particular to a water purifier double outlet waterway system and the water purifier. Background technique [0002] At present, the water system of reverse osmosis water purifiers on the market can be divided into two types: single outlet water system and double outlet water system. The single-outlet waterway system only provides pure drinking water, and the water flow is limited by the membrane flux, which cannot meet the kitchen's washing water needs; while the double-outlet waterway system can realize water supply by quality. Such as figure 1 As shown, the diversion point of the purified water in the existing dual-outlet waterway system is located after the pretreatment filter element and before the water inlet solenoid valve. When using purified water, the electric control system of the water purifier is not activated, and the mechanical control is performed by the faucet....

AI Technical Summary

Problems solved by technology

The system has the following defects: (1) limited by the water pressure of the pipeline, and under the flow restriction of the pre-treatment filter element, the outlet flow of purified water is small, which cannot meet the large amount of water demand for kitchen cleaning; (2) using When purifying water, the electronic control system cannot identify it, and the calculation of the core life is inaccurate, which may easily lead to overloading of the filter element and affect the water quality of the effluent; (3) The RO membrane can only be flushed through the waste water pipeline, resulting in insufficient flushing, and the surface of the RO membrane is easily Formation of crystals shortens the service life of the RO membrane

[0004] Although the dual-outlet cylindrical integrated water purifier disclosed in the above-mentioned prior patent application can realize double-outlet water, it can obtain both pure water and large-flow purified water, thereby satisfying various water demands of users and having The advantage of reducing wastewater discharge, but the introduction of wastewater into the clean water flow channel makes the use of wastewater as clean water only play a role in reducing wastewater discharge
