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

Embodiment 1

[0020] Example 1. attached figure 1 In the filter channel 1, the pre-filter gall 21, 22, 23 and the fine filter gall 24 provided with the inlet, outlet and concentrated water outlet are connected in series in sequence, and the water outlet of the pre-filter gall 23 is connected to the fine filter gall 24. The booster pump 6 is connected in series between the water ports; the concentrated water port of the fine filter gall 24 is connected to the concentrated water storage device 7 with the water return port through the discharge pipeline of the flow control device 4 (such as the ratio of waste water) provided with the water return port. The return water line of the return water pump 61 is connected with the water inlet line of the booster pump 6, and the connection of the return water line is specifically arranged in the line between the pre-filter gallbladder and the booster pump. The water outlet of the fine filter gall 24 is connected to the pure water interface 1b of the d...

Embodiment 2

[0028] Example 2. On the basis of Embodiment 1, the connection between the return water pipeline and the pre-filter channel is set in the connection pipeline between the booster pump 6 and the fine filter gallbladder 24, and the water purification pipeline and the water purification valve 9a are connected clean water interface 1a, as attached figure 2 structure shown in. The concentrated water outlet of the fine filter gallbladder 24 is connected to the concentrated water reservoir 7 with a water return port through the discharge pipeline provided with the flow control device 4, and the water return port is connected to the outlet pipe of the booster pump 6 through the return water pipeline with the water return pump 61 road. The water outlet of the fine filter gall 24 is connected to the pure water interface 1b of the double water outlet pressure-bearing faucet.

[0029] Open the water purification valve 9a or the pure water valve 9b of the double water outlet pressure-be...

Embodiment 3

[0040] Example 3. On the basis of Embodiments 1 and 2, the concentrated water storage 7 is set on the base of the machine, and the corresponding return water pump 61 and booster pump 6 are both set on the base.

[0041] As the second mode of Embodiment 3, on the basis of Embodiments 1 and 2, the concentrated water reservoir 7 is separated from the machine base and passed through the water hose and the discharge pipe of the fine filter gall in the filter channel of the machine base Road, and the connection of the pre-filter channel are respectively connected to form a complete circuit of the concentrated water storage tank 7 for storing the concentrated water and the return water pipeline channel. The corresponding return water pump 61 can be located either on the concentrated water storage 7 or on the machine base.

Abstract

The invention relates to the water treatment industry, and in particular relates to the filtration of drinking water. The invention discloses a double-pump water purifier switchable water production method with a concentrated drain water recovery device. Each pre-filter gallbladder and the fine filter gallbladder with water inlet, outlet and concentrated water outlet are connected in series in the filter channel in series, and the booster pump controlled by the electronic control device is connected in series between the pre-filter gallbladder and the fine filter gallbladder; The concentrated water outlet of the filter gallbladder is connected to the concentrated water storage device, and is connected to the pre-filter channel through the return pipeline, including the return water pump in the return water pipeline; the electric control device controls the return water pump to extract concentrated water during the water outlet process of the filter channel Concentrated water in the water storage device is sent through the pre-filter channel control device, or is sent together with the passing water in the pre-filtering channel, or alternately connected with the passing water in the pre-filtering channel; When the concentrated water in the middle row drops to the lower limit of water level control, the electric control device controls to turn off the return water pump, and the pre-filter channel control device controls the water supply to the pre-filter channel.

Description

technical field [0001] The invention relates to the water treatment industry, and specifically relates to the deep filtration and purification of drinking water. Background technique [0002] 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 the operation of the nanofiltration membrane filter or the reverse osmosis membrane filter, the concentrated water discharged from the concentrated water outlet in large quantities. In addition, for a wate...
