Problems solved by technology

[0003] In the prior art, pure water is also used to flush the reverse osmosis filter of the water purification system, wherein the pure water is stored in a pressure tank, and when the pressure in the pressure tank is too low, the amount of water released from the pressure tank is extremely small The flushing of the reverse osmosis filter cannot be realized, thus wasting the pressure tank to release this part of the water

Embodiment 1

[0034] Such as figure 1 , 2 As shown, in this embodiment, the water purification system includes a branch 26 arranged in parallel with the reverse osmosis filter 13, the branch 26 is provided with a pressure tank 10, and the pressure tank 10 is filtered with the reverse osmosis through the outlet pipeline 25 The device 13 is connected, and the outlet pipeline 25 is provided with a second low pressure switch 9 for detecting the pressure in the pressure barrel 10, so that the control module of the water purification system can judge whether to stop the reverse osmosis filter according to the detection value of the second low pressure switch 9 The flushing work of device 13.

[0035] When the pressure in the pressure barrel 10 was too low, the amount of water discharged from the pressure barrel 10 was extremely small, and the flushing of the reverse osmosis filter 13 could not be realized. The pressure in the pressure tank 10, before the pressure in the pressure tank 10 is too ...

Embodiment 2

[0044] Such as figure 1 , 2 As shown, in this embodiment, the pressure barrel 10 is connected to the pure water outlet of the reverse osmosis filter 13 through the water inlet pipeline 24, and the water inlet pipeline 24 is provided with a second high pressure for detecting the pressure inside the pressure barrel 10 The switch 11 enables the control module of the water purification system to judge whether to stop water intake into the pressure tank 10 according to the detection value of the second high pressure switch 11 .

[0045] The water outlet and the water inlet of the pressure tank 10 are the same opening 22 , and the opening 22 communicates with the water inlet pipeline 24 or the water outlet pipeline 25 respectively through the adapter 23 .

[0046] The water inlet pipeline 24 is provided with a first valve 15 for controlling the on-off of the pipeline.

[0047] In this embodiment, the corresponding states of the water purification system are as follows:

[0048] S...

Embodiment 3

[0060] In the present invention, the water in the pressure barrel 10 can flush the reverse osmosis filter 13 from the pure water outlet of the reverse osmosis filter 13 .

[0061] In this embodiment, the corresponding states of the water purification system are as follows:

[0062] State 1. The user closes the pure water faucet, the water purification system ends the water production mode, the second high pressure switch 11 detects the pressure in the pressure tank 10, when the pressure in the pressure tank 10 reaches the first set value of the second high pressure switch 11 , the water purification system enters the flushing mode; when the pressure in the pressure tank 10 is lower than the first set value of the second high pressure switch 11, the water purification system enters the water production mode, the first valve 15 is opened, and the flushing solenoid valve 14 is half open state, pure water enters the pressure tank 10 until the pressure in the pressure tank 10 reach...

Abstract

The invention relates to a water purification system which comprises a reverse osmosis filter and a branch arranged in parallel with the reverse osmosis filter, wherein a pressure barrel is arranged on the branch and communicated with the reverse osmosis filter through a water outlet pipeline; a second low pressure switch for detecting pressure in the pressure barrel is arranged on the water outlet pipeline; and a control module of the water purification system judges whether to stop flushing operation of the reverse osmosis filter according to a detection value of the second low pressure switch. The invention further relates to a control method of the water purification system. The control method comprises the steps of allowing the second low pressure switch to detect the pressure in thepressure barrel when the reverse osmosis filter is flushed by pure water in the pressure barrel, and allowing the water purification system to finish a flushing mode when the pressure in the pressurebarrel is less than a first setting value of the second low pressure switch. The low pressure switch is used for detecting the pressure in the pressure barrel in a flushing process of the reverse osmosis filter; before the pressure is too low, the control module of the water purification system stops the flushing operation of the reverse osmosis filter; and therefore, the waste of the water from the pressure barrel is avoided.

Description

technical field [0001] The invention relates to a water purification system and a control method thereof. Background technique [0002] The water purification system is a type of drinking water purification equipment that is especially in line with China's national conditions and market. It can provide safe and pure water, especially the large flow water purification system has gradually become the main popular water purification system in the market. It not only has a large water flow , and eliminates the pressure barrel that can breed bacteria and create odors. In the prior art, raw water is generally used to flush the reverse osmosis filter of the water purification system, so that the reverse osmosis membrane of the reverse osmosis filter is soaked in water with a higher TDS value, and natural osmosis occurs to balance the concentration before and after the reverse osmosis membrane. As a result, the first glass of water in the water purification system has a higher TDS ...
