Problems solved by technology

However, when the user takes water again after a long interval of time, there will be concentrated water remaining on the reverse osmosis membrane filter element, so when water is produced again, the concentrated water remaining on the reverse osmosis membrane filter element will mix with the raw water newly entering the filter element, resulting in The TDS value of pure water is high, even close to the TDS value of raw water
Since the mainstream water purifiers on the market no longer use pressure tanks as water storage devices, but directly connect pure water to the user's faucet, the dissolved solid content in the water taken by the user will be high, that is, The water taken is impure

Embodiment 1

[0020] Self-rinsing water purifiers, such as figure 1 As shown, it includes a water inlet 1, a pressure reducing valve 2, a pre-filter element 3, a second solenoid valve 41, a second tee 51, a booster pump 7 and a reverse osmosis membrane filter element 8 connected in series, and the reverse osmosis membrane filter element 8 includes The pure water outlet of the filter element and the concentrated water outlet of the filter element, the pure water outlet of the filter element is connected with the first three-way 52, the first three-way 52 is connected with the one-way valve 9, and the one-way valve 9 is connected with the pure water outlet 11. The water pressure sensor 10 is used to detect the water pressure between the pure water outlet 11 and the one-way valve 9 and transmit it to the controller.

[0021] The controller uses a single-chip microcomputer.

[0022] A third three-way 54 , a throttle valve 13 , a fourth three-way 53 and a concentrated water outlet 12 are connec...

Embodiment 2

[0030] If the pure water outlet 11 is closed, because the water cannot flow out, the water pressure between the check valve 9 and the pure water outlet 11 is high pressure, and the water pressure sensor 10 transmits the signal to the controller. The controller controls the fourth electromagnetic valve 43 to open, and the pure water produced by the reverse osmosis membrane filter element 8 flows through the fourth electromagnetic valve 43 and then enters the water tank 6, at this time the magnetic float 67 rises with the water. This process is the water tank inlet working condition.

[0031] The controller controls the opening of the first solenoid valve 42 and the third solenoid valve 44, and simultaneously controls the closing of the second solenoid valve 41 and the fourth solenoid valve 43, so that the pure water in the water tank 6 flows through the pipe 62 in the water tank 6, the first Electromagnetic valve 42, second three-way 51, reverse osmosis membrane filter element ...

Embodiment 3

[0035] After the filter element is flushed, the controller controls the first solenoid valve 42, the third solenoid valve 44 and the booster pump to be closed after a delay of 1 minute. If the user does not open the pure water outlet 11 to take water within 4 hours, the controller will repeat the water tank inlet condition and the filter element flushing condition by itself.

Abstract

The invention relates to a water purifier, and discloses a self-flushing water purifier. The self-flushing water purifier comprises a water inlet (1), a front filter element (3), a booster pump (7) and a reverse osmosis membrane filter element (8) which are connected in series in sequence, a water tank (6), a water pressure sensor (10), a one-way valve (9) and a pure water outlet (11); the reverse osmosis membrane filter element (8) comprises a filter element pure water outlet and a filter element concentrated water outlet; the filter element pure water outlet is connected with a first tee joint (52); a second tee joint (51) is arranged between the front filter element (3) and the booster pump (7); the water inlet of the water tank (6) is connected with the first tee joint (52); the water outlet of the water tank (6) is connected with a first electromagnetic valve (42); the first electromagnetic valve (42) is connected with the second tee joint (51). Due to the adoption of the technical scheme, pure water stored in the water tank can clean the reverse osmosis membrane filter element automatically, so that the purity of the water taken by a user is ensured.

Description

technical field [0001] The invention relates to a water purifier, in particular to a water purifier with the function of automatically flushing filter cores. Background technique [0002] Water purifiers using reverse osmosis membrane filter elements have been widely used in homes or offices. However, when the user takes water again after a long interval of time, there will be concentrated water remaining on the reverse osmosis membrane filter element, so when water is produced again, the concentrated water remaining on the reverse osmosis membrane filter element will mix with the raw water newly entering the filter element, resulting in The TDS value of pure water is high, even close to the TDS value of raw water. Since the mainstream water purifiers on the market no longer use pressure tanks as water storage devices, but directly connect pure water to the user's faucet, the dissolved solid content in the water taken by the user will be high, that is, The water taken is i...
