Switching water production method of double outlet pure water machine with concentrated drain water recovery device

Abstract

The invention relates to a water treatment industry, and concretely relates to filtering of drinking water. The invention discloses relates to a double-outlet purified water machine switching water-production method having a discharged thick water recovery device. According to the invention, the booster pumps connected in series are arranged between a preposition filter bladder and a fine filter bladder; a thick water receiver with a backwater port is communicated with a discharged thick water outlet of the fine filter bladder, the backwater port is communicated with a booster pump inlet pipeline; the water outlet of the fine filter bladder is communicated with a pure water interface of a double-outlet faucet, and a water sensor is arranged on the water outlet of the fine filter bladder, the booster pump outlet pipeline is communicated with a purified water interface of the double-outlet faucet through a first purified water pipeline of the water sensor; a purified water valve or a pure water valve are opened for triggering the corresponding water sensor, an electric signal corresponding to purified water outlet or pure water outlet are output to an electric control apparatus for driving the booster pump for extracting the discharged thick water in the thick water receiver, or conveying is carried out with purified water in the preposition filter bladder, or successive conveying is respectively carried out with the purified water in the preposition filter bladder, and the discharged thick can be individually flowed out from the purified water interface or the pure water interface.

Description

[0001] Prior application number: 201510182692.0 [0002] Title of prior application: Switching water production method for double-outlet pure water machine with drain concentrated water recovery device technical field [0003] The invention relates to the water treatment industry, and specifically relates to the deep filtration and purification of drinking water. Background technique [0004] During the use of the water purifier, most of the water consumption is washing water, accounting for about 97%, and drinking water only accounts for about 3%. Higher drinking water. Existing single-outlet water purifiers use the water filtered by all the filters in the filter channel of the machine regardless of whether they use washing water or drinking water, resulting in a waste of a large amount of high-grade water treatment resources and a serious consumption of fine filters with high filtration accuracy. The service life of the filter is also wasted at the same time along with t...

Problems solved by technology

However, the three-pipe gooseneck faucet has brought a new situation: when the spool is closed, due to the water pressure in the machine, it takes 10 to 15 seconds for the water to flow out of the faucet outlet.

In this process, the water droplets flow drop by drop. Users are not used to it. It is generally believed that there is a quality problem in the water purification faucet, and it is difficult to accept this waste of water.

Above-mentioned defect and deficiency have influenced the popularization of water purifier
