Fig. 3 is a flushing schematic diagram of the automatic flushing device according to an example of the present invention.
As shown in fig. 3, in step S310, the controller detects whether the state of the water purifier meets a flushing start condition, and when the state meets the flushing start condition, controls the flushing solenoid valve to open, so that the water flowing out from the water outlet of the water treatment system passes through the water quality detector on the flushing pipeline and is then discharged from the concentrated water outlet. The flushing starting condition may include at least one of a condition that the water purifier starts to produce water for the first time, a condition that the water purifier stops producing water after water production operation, and a condition that the controller counts a set flushing period, that is, flushing can be started when any one condition is met.
In step S320, the water quality detection data detected by the water quality detector is received, and whether the current water quality meets the standard is determined according to the received water quality detection data. The specific process of step S320 may include: and receiving water quality detection data detected by the water quality detector, comparing the received water quality detection data with a set water quality standard value, and determining that the current water quality reaches the standard when the water quality detection data is less than or equal to the set water quality standard value. Wherein, the set water quality standard value is determined according to the water quality condition of local tap water.
In step S330, if the current water quality meets the standard, the flushing solenoid valve is controlled to close, otherwise, the flushing is continued.
In the following, the flushing starting condition including the water purifier starting the water making for the first time is taken as an example, and the flushing principle of the automatic flushing device is further explained.
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, a 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 water quality detector such as the TDS detector and the flushing check valve, 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 condition of the water quality of local tap water, and the set water quality standard value can be set. And when the set water quality standard value 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 to the controller of purifier and stops system water signal, and the controller of purifier gives and washes the solenoid valve shut off signal, washes the solenoid valve stop work, and the first installation is washed and is ended. 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 initial installation of the water purifier during the initial installation of the water purifier.
In the following, the flushing principle of the automatic flushing device will be further explained by taking the example that the flushing starting condition includes that the water purifier stops producing water after the water production 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 purifier stopped system water, the controller of purifier sent opening signal and gives and washes the solenoid valve, washes the solenoid valve and begins work, and the water that will rearmounted filter core is terminal and the pipeline discharges through water quality testing appearance such as TDS detector and washing check valve, and after the quality of water detected value of discharged water reached the quality of water standard value of setting for, the quality of water standard value of setting for can be 10. And when the set water quality standard value 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 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 making operation can be combined with the condition of timing to the flushing period, and the flushing period can be set in the time when the water peak is missed, and the flushing is carried out once every other set flushing period. 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 can completely solve the problem that the TDS value of the initial water produced by the reverse osmosis water purifier is higher for the flushing of the water purifier during shutdown after use.
The utility model discloses purifier and automatic flushing device thereof installs one set of simple and easy device additional on the purifier, and this set of device health safety does not have any pollution, can solve the manual problem of not thorough, not convenient to wash of first installation completely, solves the problem that reverse osmosis purifier initial stage product water TDS value is higher than normal completely, lets the user drink fresh and alive water constantly.
