Water-free reverse osmosis water purifying machine

Abstract

The invention discloses a water-free reverse osmosis water purifying machine, which comprises a preprocessor and a reprocessor. The preprocessor and the reprocessor are serially arranged in the water intake pipe. Water flows into the reprocessor after being treated with the preprocessor. The reprocessor, which is a closed vessel, is seperated into a condensed-water region and a pure-water region by the reverse osmosis film. Pure water flows out through the outlet of the pure-water region. Condensed water is produced during the operation of the reprocessor and collected in a accumulator. The outlet of the accumulator is connected with a pipe through drain lines and the pipe is connected directly with the inlet of the water purifying machine. The outlet of the accumulator is also connected with the inlet of the reprocessor through reflux lines. Since the water purifying machine collects the discharged condensed water and adopts the recycling equipment, washing procedure of the reverse osmosis film is no longer needed. The above water purifying machine helps to save water and extend the service life of the filter core of the preprocessor.

Description

technical field [0001] The invention relates to a water purifier, in particular to a daily-use waste water-free reverse osmosis water purifier. Background technique [0002] Such as figure 1 As shown, the daily reverse osmosis water purifier in the prior art includes a pretreatment system and a deep treatment system. The pretreatment system is composed of several preprocessors 2' equipped with filter elements. One by one in series, wherein the water inlet of the first preprocessor is connected with the source water through the water supply pipe 1'; the deep treatment system is composed of a deep processor containing a reverse osmosis membrane, and the deep processor is a closed container, and the reverse osmosis membrane connects the deep processor Divided into pure water area 5' and concentrated water area 6', the pure water area is connected with an outlet pipe 7' for taking pure water, and the concentrated water area is provided with a water inlet and an outlet; It is c...

Problems solved by technology

[0006] The disadvantage of the reverse osmosis water purifier structure in the above-mentioned prior art is that the concentrated water discharged through the waste water ratio has been filtered by the pretreatment system. Although its impurity content is quite different from that of pure water, its water quality is still higher than or It is equivalent to ordinary tap water (mainly because the concentration of minerals is higher than that of tap water), but here it can only be discharged in the form of waste water, causing huge waste

Normally, 3 cubic meters of concentrated water will be drained for every cubic meter of pure water produced; in addition, this structure also requires an independent reverse osmosis membrane flushing program, and the water used in the flushing process will also be used as waste water through the flushing solenoid valve control Draining, while wasting water, it also increases the workload of the preprocessor and affects the working life of the filter element in the preprocessor
