Water purifying machine with pure-water-membrane-soaking function during stopping resting

Abstract

The invention discloses a water purifying machine with the pure-water-membrane-soaking function during stopping resting. The water purifying machine comprises an original water end, a water feeding electric valve, a filter element mechanism, a boosting pump and a RO membrane module, and also comprises a check valve, a pure-water storage tank, a high-water-level floating ball switch, a low-water-level floating ball switch, a water feeding pump and a micro-wastewater-ratio-combination electromagnetic valve, wherein the original water end, the water feeding electric valve, the filter element mechanism, the boosting pump and the RO membrane module are sequentially connected through a pipe. A pure water outlet in the RO membrane module is connected with a water returning pipe and a water discharging pipe; the water returning pipe is provided with the check valve, and the water discharging pipe is provided with the pure-water storage tank, the water feeding pump and a pure water faucet; a thick water outlet in the RO membrane module is connected with the micro-wastewater-ratio-combination electromagnetic valve, and the micro-wastewater-ratio-combination electromagnetic valve is connected with a sewer for discharging; the high-water-level floating ball switch and the low-water-level floating ball switch are arranged in the pure-water storage tank. By means of the water purifying machine with the pure-water-membrane-soaking function during stopping resting, in the using process of a traditional RO water purifying machine, the problem that as the traditional RO water purifying machine is located in thick-water membrane soaking during resting stopping, the initial water-making TDS value of the RO water purifying machine is higher than the standard value is solved, and the membrane-surface scaling problem caused when a RO membrane sheet is soaked with thick water for a long time is solved.

Description

technical field [0001] The invention relates to the technical field of water purifiers, in particular to a pure water bubble membrane technology. Background technique [0002] China is a country with scarce water resources. The limited water source is seriously polluted, and the water environment continues to deteriorate, seriously threatening the safety of drinking water in urban and rural areas. Therefore, surface water and groundwater must be purified before they can be used as drinking water. Now the core drinking water treatment technology is membrane filtration technology. One of them is reverse osmosis membrane (RO membrane) filtration. The filter pore size is 0.0001 micron, which can completely remove all harmful substances in water, and only keep water molecules to produce pure water. Its effect is the best solution in membrane treatment, but its One of the biggest disadvantages is that the RO membrane is soaked in concentrated water for a long time when the water...

Problems solved by technology

[0003] The purpose of the present invention is to provide a water purifier with the function of pure water bubble film when the machine is still at rest, so as to solve the RO net effect caused by the thick water bubble film when the traditional RO water purifier is in use. The problem that the TDS value of the initial water production of the water machine is higher than the standard value, and the problem of fouling on the membrane surface caused by the long-term immersion of the RO membrane in concentrated water
