Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it should be understood that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, the present embodiment provides a water treatment system, which includes a raw water tank 2, a waste water tank 3, a composite filter element 8, a self-priming pump 7, a first pipeline, a second pipeline, a third pipeline, a fourth pipeline, a control valve, and a pure water tank 11.
The raw water tank 2 and the waste water tank 3 are connected into a whole. The composite filter element 8 is a composite structure comprising a pretreatment filter element, a reverse osmosis membrane filter element and a post-filter element, and is provided with a raw water end, a pure water end and a concentrated water end. Former water tank 2 passes through the former water end intercommunication of self priming pump 7 with composite filter element 8 through first pipeline, and composite filter element 8's pure water end is passed through the control valve and is put through with second pipeline and third pipeline respectively, and the other end and the former water tank 2 of second pipeline are connected, and the other end and the water inlet of pure water tank 11 of third pipeline are connected. The concentrated water end of the composite filter element 8 is communicated to the waste water tank 3 through a fourth pipeline, and a switch valve 10 for controlling the on-off of the fourth pipeline is arranged on the fourth pipeline. The control valve is a three-way electromagnetic valve 9.
The raw water tank 2 is provided with a second water level detection device 5 and a third water level detection device 1. The second water level detection device 5 is arranged at the bottom of the original water tank 2, and the third water level detection device 1 is arranged at a preset position on the side wall of the original water tank 2. The waste water tank 3 is provided with a first water level detection device 4 at a full water level. The full water level and the bottom of the pure water tank 11 are provided with a fourth water level detection device 14 and a fifth water level detection device 15, respectively.
When the user took first cup water, the water of former water tank 2 passed through first pipeline and got into composite filter element 8 through self priming pump 7 and prepared out the pure water, then control three way solenoid valve 9 switches on the second pipeline and close the third pipeline. So, first cup water has avoided the user to drink the higher water of first cup TDS value in the second pipeline backward flow to former water tank 2, has avoided the waste of water resource simultaneously. Then, the three-way electromagnetic valve 9 is controlled to open the third pipeline and close the second pipeline, so that the user can use the three-way electromagnetic valve normally. Simultaneously, still be equipped with first TDS probe 6 between former water tank 2 and first pipeline, can make the user know the change of quality of water in the former water tank 2 at any time, guarantee that the user drinks the water that the TDS value is normal.
In this embodiment, a second TDS probe 13 is further provided in the pure water tank 11, and a straight-flow pump 16, a heating device 17 and a water outlet 18 are provided at the outlet of the pure water tank 11. When the user takes, can decide whether to heat water according to user's self demand, satisfy user's drinking demand. The design of second TDS probe 13 can make the user know the TDS value of the pure water of preparing in the pure water case 11 at any time to know the quality of water change of pure water at any time, and can drink or prepare again according to actual conditions, let the user drink to the water that is fit for human health. When the pure water tank 11 is prepared again, the water in the pure water tank can be poured into the raw water tank 2, and waste is avoided.
When the water in the pure water tank 11 reaches the fourth water level detection device 14 at the full water level, the water treatment system stops water production; when the water in the pure water tank 11 reaches the fifth water level detecting device 15 located at the bottom of the pure water tank 11, water production is started. The top of the pure water tank 11 is further provided with a vent 12, which can keep the air pressure inside the pure water tank 11 equal to the external air pressure, so that the user can take water more smoothly.
When the water level in the raw water tank 2 is lower than the third water level detection device 1, the water level in the waste water tank 3 is lower than the first water level detection device 4, and the water level in the pure water tank 11 reaches the fourth water level detection device 14, the three-way electromagnetic valve 9 is controlled to conduct the second pipeline and close the third pipeline, and the switch valve 10 is controlled to open and control the self-priming pump 7 to work. So set up, through 7 work of self priming pump with the surplus small part water washing composite filter element 8, ooff valve 10 and the fourth pipeline that lie in third water level detection device 1 in former water tank 2, can make composite filter element 8 and ooff valve 10 will not block up, prolonged the life of reverse osmosis membrane filter element and ooff valve 10, improved the life of purifier, reduce user's maintenance frequency, promote user's use and experience.
Meanwhile, a first alarm device and a second alarm device are respectively arranged in the raw water tank 2 and the waste water tank 3, and the first alarm device and the second alarm device are respectively electrically connected with the second water level detection device 5 and the first water level detection device 4. When the water in the raw water tank 2 reaches the second water level detection device 5 or the water in the waste water tank 3 reaches the first water level detection device 4, the first alarm device or the second alarm device gives an alarm, and meanwhile, the water treatment system stops making water. The user can judge whether former water tank 2 need add water or whether waste water tank 3 need change water according to the alarm sound type of difference to user's use experience has been improved. The water in the waste water tank 3 can be used for mopping, watering flowers, washing clothes and the like, so that waste of water resources is avoided.
When the user stopped using water again after a period, 2 normal waters of former water tank pass through self priming pump 7 and get into composite filter element 8 in, the waste water of production passes through in ooff valve 10 gets into waste water tank 3. The process is to wash a part of water in the original water tank 2 with the composite filter element 8, the switch valve 10 and the fourth pipeline, so that the composite filter element 8 and the switch valve 10 cannot be blocked, and the service life of the composite filter element is prolonged.
As another embodiment, referring to FIG. 2, the composite filter element 8 in the water treatment system can be replaced by a pretreatment filter element 19, a reverse osmosis membrane filter element 21 and a post-filter element 20 which are arranged independently and connected in sequence. The raw water end is communicated with the raw water tank 2 through the first pipeline and the pretreatment filter element 19, and the pure water end is communicated with the second pipeline and the third pipeline through the post-positioned filter element 20. Second pipeline one end and three way solenoid valve 10 intercommunication, the other end merges into the first pipeline between former water tank 2 and self priming pump 7.
As another embodiment, as shown in fig. 2 and 3, one end of the second pipeline is communicated with the three-way solenoid valve 10, and the other end is merged into the first pipeline between the raw water tank 2 and the self-priming pump 7.
As another embodiment, the composite filter element 8 in the water treatment system can be replaced by a separately arranged reverse osmosis membrane filter element 21.
