The following describes a flushing method of the automatic flushing device by taking a flushing start condition including first starting the water purifier to produce water as an example.
When the water purifier is first installed, after each stage of filter element is installed on the water purifier, water is electrified, and a pure water outlet, such as a tap, is closed. At this time, the water purifier is in a state of opening the water production, the controller of the water purifier gives an opening signal to the flushing electromagnetic valve, the flushing electromagnetic valve is opened, water at the tail end of the rear filter element and on the pipeline is discharged through the water quality detector such as the TDS detector and the flushing check valve, and when the water quality detection value of the discharged water reaches a set water quality standard value, the set water quality standard value is determined according to the water quality condition of local tap water, and the set water quality standard value can be. When the set standard value of the water quality is 10, determining that the water quality meets the standard when the detected TDS value is less than or equal to 10. The TDS detector sends a signal for stopping water production to a controller of the water purifier, the controller of the water purifier gives a signal for closing a flushing electromagnetic valve, the flushing electromagnetic valve stops working, and the first installation flushing is finished. The whole process is completely and automatically flushed without on-site monitoring by people.
The automatic flushing device can completely solve the problems of incomplete and inconvenient manual flushing in the first installation of the water purifier.
The method of flushing the automatic flushing device will be further described below taking a flushing start condition including after stopping the water production of the water purifier after the water production operation as an example.
When a user uses the pure water outlet, such as a faucet, to take water, the flushing electromagnetic valve is in a closed state, water flows out from the pure water outlet, and the user normally takes water. After the water purifier stops making water, the controller of the water purifier sends an opening signal to the flushing electromagnetic valve, the flushing electromagnetic valve starts to work, water at the tail end of the rear filter element and on the pipeline is discharged through the water quality detector such as the TDS detector and the flushing check valve, and when the water quality detection value of the discharged water reaches the set water quality standard value, the set water quality standard value can be 10. When the set standard value of the water quality is 10, determining that the water quality meets the standard when the detected TDS value is less than or equal to 10. At this time, the flushing solenoid valve receives a closing signal of the controller of the water purifier, the flushing solenoid valve stops working, and the water discharge is finished. Wherein, whether the purifier is in the state of stopping producing water can be judged by detecting whether the waste water ratio electromagnetic valve is in the closed state.
In addition, the condition after stopping the water production after the water production operation may be combined with the condition of timing to the flushing cycle, and the flushing cycle may be set to a period in which the peak of water consumption is missed, and flushing is performed once every flushing cycle set at intervals. The flushing period is set at a fixed time period, and the flushing time is not in the water peak period, and is generally between 0 and 4 hours in the early morning. Flushing and water intake may be performed simultaneously if water is just drained when it is encountered. The drain volume per flush may be 100-500ml.
The automatic flushing device completely solves the problem of high TDS value of the initial water produced by the reverse osmosis water purifier by using the flushing method of stopping the water purifier after the water purifier is used.
The water purifier and the automatic flushing device and the flushing method thereof in the embodiment of the invention are characterized in that a simple device is additionally arranged on the water purifier, the device is sanitary and safe, has no pollution, can completely solve the problems of incomplete and inconvenient manual flushing in the first installation, completely solve the problem of high TDS value of the initial water production of the reverse osmosis water purifier, and enable a user to drink fresh and alive water at any time.
