Water purification machine capable of producing fresh purified water

Abstract

The invention discloses the structure and application method of water purification machine capable of producing fresh purified water. The water purification machine comprises a water pump, an RO membrane group, a switch and a power supply, wherein the purified water pipe of the RO membrane group is connected with a purified water return pipe, a concentrated water pipe is connected with a concentrated water return pipe, the purified water return pipe and the concentrated water return pipe are communicated with a water inlet pipe in front of the water pump, the concentrated water pipe is provided with a concentrated water electromagnetic valve, the purified water pipe at the rear of the purified water return pipe is provided with a purified water electromagnetic valve, and the opening and closing of the concentrated water electromagnetic valve and the purified water electromagnetic valve are controlled by a control panel. By the structure and the application method, unqualified purifiedwater initially produced by the water purification machine and concentrated water produced at the same time enter the water inlet pipe of the RO membrane group again and are filtered again, and accordingly the produced purified drinking water is fresh and qualified while water saving is achieved. In addition, the water purification machine is simple in structure, convenient and flexible to use, diversified in application method and capable of guaranteeing water quality.

Description

technical field [0001] The invention relates to a household reverse osmosis pure water machine. Background technique [0002] Currently on the market for household water purifiers, the pure water produced by the initial work of the pure water machine usually flows out from the tap or flows into the water storage tank, and the concentrated water is drained away, while the RO membrane has the characteristics of unqualified water production in the initial water production, which will cause If the water quality is not up to standard, if the initial water production is not used and the concentrated water is drained, it will cause water waste. There is also a pure water machine on the market where the initial water production is discharged with the waste water and does not enter the water storage tank. This method will cause water waste; The disadvantage of the initial water flow back into the water inlet pipe is that the operation and structure are complicated. At the same time,...

[0002] Currently on the market for household water purifiers, the pure water produced by the initial work of the pure water machine usually flows out from the tap or flows into the water storage tank, and the concentrated water is drained away, while the RO membrane has the characteristics of unqualified water production in the initial water production, which will cause If the water quality is not up to standard, if the initial water production is not used and the concentrated water is drained, it will cause water waste

There is also a pure water machine on the market where the initial water production is discharged with the waste water and does not enter the water storage tank. This method will cause water waste; The disadvantage of the initial water flow back into the water inlet pipe is that the operation and structure are complicated. At the same time, the user of the pure water machine artificially controls the backflow time is inaccurate and the water quality is not guaranteed.
