When the purifier was installed for the first time, on the filter core dress of at all levels gone up the purifier, the circular telegram of logical water, pure water delivery port for example tap closed. At the moment, the water purifier is in a state of opening 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 in the pipeline is discharged through the flowmeter and the flushing check valve, when the total flow of the discharged water reaches a set flow value, the flowmeter sends a water production stopping signal to the controller of the water purifier, the controller of the water purifier gives a closing signal of the flushing electromagnetic valve, the flushing electromagnetic valve stops working, and the first installation and flushing are finished. Wherein, when the set flow value is 30L, the water quality is determined to meet the standard when the detected total flow of the discharged water is more than or equal to 30L. The whole process is monitored in the field without manpower, and the washing is completely automatic and thorough.
The automatic flushing device can completely solve the problems of incomplete and inconvenient manual flushing in the first installation of the flushing method for the first installation of the water purifier.
Hereinafter, the flushing method of the automatic flushing device will be further described by taking as an example that the flushing start condition includes that the water purifier stops producing water after the water producing operation.
When a user takes water from the pure water outlet such as a faucet, the flush solenoid valve is in a closed state, water flows out from the pure water outlet, and the user takes water normally. After the water purification machine stops producing water, the controller of the water purification machine sends an opening signal to the flushing electromagnetic valve, the flushing electromagnetic valve starts to work, water at the tail end of the post-filter element and in the pipeline is discharged through the flowmeter and the flushing check valve, and when the total flow of the discharged water reaches a set flow value, the set flow value is 350ml for example. When the set flow value is 350ml, the water quality is determined to meet the standard when the detected total flow of the discharged water is more than or equal to 350 ml. At this time, the flushing electromagnetic valve receives a closing signal of a controller of the water purifier, the flushing electromagnetic valve stops working, and water drainage is finished. Wherein, can judge whether the purifier is in the state of stopping system water through whether detection waste water ratio solenoid valve is in the closed condition.
In addition, the condition after stopping the water production after the water production operation can be combined with the condition of timing to the flushing cycle, and the flushing cycle can be set in the time when the water consumption peak is missed, and the flushing is carried out once every other set flushing cycle. The rinse cycle is set at a fixed period of time, with the time of rinsing avoiding a peak of water usage, typically between 0 and 4 hours in the morning. Flushing and water intake can be performed simultaneously if drainage is just achieved when water intake is encountered. The water displacement per flush may be 100-.
The automatic flushing device completely solves the problem that the TDS value of the initial water production of the reverse osmosis water purifier is higher by adopting the flushing method of the water purifier which stops after use.
The water purifier and the automatic flushing device and the flushing method thereof provided by the embodiment of the invention are characterized in that a set of simple device is additionally arranged on the water purifier, the device is sanitary, safe and pollution-free, the problems of incomplete and inconvenient manual flushing in the first installation can be completely solved, the problem of high TDS value of initial water production of the reverse osmosis water purifier is completely solved, and a user can drink fresh and live water at any time.
