Embodiment 1

[0041] Such as figure 1 As shown, the water purification unit in this embodiment also includes a pre-filter and a post-filter 21, and the RO reverse osmosis filter is located between the pre-filter and the post-filter 21, wherein the pre-filter Including a first pre-filter 10, a second pre-filter 11 and a third pre-filter 12, the first pre-filter 10 filter element is a 5 micron melt-blown polypropylene filter element, the second pre-filter 11 filter element It is a granular activated carbon filter element, the third pre-filter 12 filter element is a 1 micron melt-blown polypropylene filter element, the post-filter 21 is an activated carbon filter, and the activated carbon filter is connected to a pure water faucet 22 through a pipeline .

Embodiment 2

[0043] When the user opens the pure water faucet 22, the system starts the water inlet solenoid valve 14 and the booster pump 16, and the tap water enters the pipeline from the tap water source 2, and passes through the first pre-filter 10 and the second pre-filter 11 in sequence , the third pre-filter 12, and then through the low-pressure switch 13, the water inlet solenoid valve 14, the water inlet TDS probe 15, the temperature sensor 9, and the booster pump 16 enter the RO reverse osmosis filter 17, and the filtered The pure water comes out of the pure water outlet of the RO reverse osmosis filter 17, passes through the pure water end check valve 18, the pure water end high pressure switch 19, the water outlet TDS probe 20, enters the post filter 21, and then passes through the pure water end The water tap 22 flows out into the water receiving container of the user. Since a large amount of concentrated water will be generated in the process of preparing pure water, the gener...

Embodiment 3

[0045] When the user turns on the hot water switch of the domestic faucet 1, the system starts the water inlet solenoid valve 14 and the booster pump 16, the flushing solenoid valve 8 is opened, and the tap water enters the pipeline from the tap water source 1, and passes through the first pre-filter 10, The second pre-filter 11, the third pre-filter 12, and then enter the RO reverse osmosis filter through the low pressure switch 13, the water inlet solenoid valve 14, the water inlet TDS probe 15, the temperature sensor 9, and the booster pump 16 In 17, it flows out from the concentrated water outlet, passes through the flushing solenoid valve 8 and the softening filter 24, enters into the kitchen treasure heater 4 through the water inlet of the kitchen treasure heater 4, and is heated in the kitchen treasure heater 4. After heating The water enters in the living faucet 28 through the water outlet of the kitchen treasure heater 4.

Abstract

The invention discloses a water bar system adopting a double circulation mode. The system comprises a heating unit and a water purification unit, wherein the water purification unit comprises an RO (reverse osmosis) filter, concentrated water produced by the RO filter enters into the heating unit via a wastewater proportioner, a water outlet of the heating unit is connected with a tap water source, the tap water source is connected with a water inlet of the water purification unit, an overflow electromagnetic valve is arranged between the wastewater proportioner and a water inlet of the heating unit, and a normally open electromagnetic valve is arranged between the RO filter and the water inlet of the heating unit. The overflow electromagnetic valve and the normally open electromagnetic valve are added to the system, TDS (total dissolved solids) in the system cannot be too high in the double circulation mode, and stable operation of the system is guaranteed; different circulation modescan be switched according to the water temperature, the purification efficiency of the RO filter is improved and the service life of the RO filter is prolonged.

Description

technical field [0001] The invention belongs to the technical field of household electrical appliances, and in particular relates to a water bar system in double circulation mode. Background technique [0002] At present, with the development of industrialization and the improvement of people's living standards, the pollution of water resources is becoming more and more serious, and people are paying more and more attention to the quality of water resources. For this reason, more and more water purification technologies are popularized. In the general civilian field, corresponding water purification products have also been promoted. When the reverse osmosis water purifiers on the market produce water, a large amount of concentrated water will be produced, and the concentrated water will be directly discharged into the sewer. caused serious waste. [0003] The manufacturers of reverse osmosis water purifiers in the prior art have processed concentrated water, but most of the...
