Problems solved by technology

[0002] Due to the characteristics of the RO membrane (pure water and concentrated water are mixed at rest), the pure water quality TDS value of pure water is high when it is first started, and it needs to be rinsed for about 2 minutes before it can be qualified. Waiting, and water will be wasted, high-concentration concentrated water will easily block the pores of the RO membrane and reduce the service life of the RO membrane

Embodiment approach

[0011] Such as figure 1 The fresh and pure water-saving pure water machine shown is composed of a primary filter group, a water pump, and a RO membrane group. According to the direction of water inlet flow—water pump 4 is connected to RO membrane group 5, and according to the direction of pure water outlet flow—pure water pipe 11 The pure water return pipe 13 is connected before the pure water check valve 12, and the pure water return valve 12 of the pure water pipe 11 is provided with a pure water high pressure switch 22, and a pure water return check valve 14 is arranged on the pure water return pipe 13 . According to the direction of the water inlet flow—the pure water return pipe 13 is connected to the water inlet pipe 1 between the rear of the primary filter element group 15 and the front of the water pump 4; figure 2 Shown: the power output line of the power supply 17 is connected to the delayed power-off control board 19, the pure water high pressure switch 22 inlet a...

Abstract

The invention discloses a fresh and pure water machine having water saving effect, which is composed of a primary filter core group, a water pump, and an RO membrane group. A pure water backflow pipe is connected to a water inlet pipe after the primary filter core group and before the water pump. Two output lines on a delay power cut control board are respectively connected to the water pump and a water inlet electromagnetic valve. The water inlet pipe after the water inlet electromagnetic valve is connected to a pressure-reduced micro pressure water storage barrel and a concentrated water backflow pipe which is provided with a concentrated water high pressure switch and a four-way valve. An input line of a 24-hour timing control board is connected to a power supply while an outlet line is connected to the water pump. When the fresh and pure water machine is switched on, TDS value of water quality of pure water can reach the standard quickly. The machine is free of waiting for water or has short waiting time, is free of or is less in waste on water, and is effectively prolonged in service life of the RO membrane.

Description

technical field [0001] The invention relates to a domestic pure water machine, in particular to a large-flow ready-to-drink household pure water machine without a pressure storage tank. Background technique [0002] Due to the characteristics of the RO membrane (pure water and concentrated water are mixed at rest), the pure water quality TDS value of pure water is high when it is first started, and it needs to be rinsed for about 2 minutes before it can be qualified. Waiting will waste water, and concentrated water with high concentration will easily block the pores of the RO membrane and reduce the service life of the RO membrane. Contents of the invention [0003] The purpose of the present invention is to provide a fresh and pure water-saving device that can quickly pass the TDS value of pure water after starting up, does not need to wait for water (or the waiting time is short), does not waste water or wastes less water, and effectively prolongs the service life of the...
