In order to meet the requirement of further hot water production, a water pump 52 may be disposed between the pure water outlet channel 2 and the heating element 51.
The setting and function application principle of the waterway system is as follows:
firstly, in a conventional pure water making mode, a user selects a pure water output end 20 to get water, an external water source is input from the raw water input end 10, and is sequentially input to the water inlet 61 through the preposed filter element assembly 13, the water inlet valve 12 and the pressurizing assembly 11 under the guidance of the raw water inlet flow channel 1; the pure water is filtered by the reverse osmosis filter element assembly 6, wherein the pure water is partially output from the pure water port 62, the water discharge control valve 201 is in an open state, and water is guided by the pure water outlet runner 2 to sequentially pass through the water discharge control valve 201, the first one-way valve 21, the high-pressure switch 22 and the post-filter element assembly 23 to be output to the pure water output end 20, so that the pure water at normal temperature is output.
Or the user selects the hot water output end 50 to take water, the pure water filtered by the reverse osmosis filter element assembly 6 flows to the water pump 52 under the guidance of the hot water outlet flow passage 5, and is heated by the heating assembly 51 and then output by the rear hot water output end 50, and the heated hot pure water is output.
The wastewater generated by the reverse osmosis filter element assembly 6 is output from the wastewater outlet 63 and is guided by the wastewater drainage flow channel 3 to the wastewater output end 30 through the wastewater control valve 31.
Secondly, when the waterway system is shut down over a period of time, the pure water side position in the reverse osmosis cartridge module 6 causes its TDS value to rise as the shutdown progresses. When the computer is started again to fetch water, the water-removing mode is required to be executed. In the mode of removing old water, external water is input into the water inlet 61 through the raw water inlet channel 1 and is filtered by the reverse osmosis filter core assembly 6; at this time, the pure water side of the reverse osmosis filter element assembly 6 is obtained as old water with a higher TDS value.
Then, based on different old water treatment modes, or selecting to discharge all old water, at this time, the waste water control valve 31 is opened, the drain control valve 201 is closed, the old water control valve 41 is opened, and the generated old water is merged with the waste water and then directly discharged to the waste water output terminal 30.
Or selecting the form of partial discharge and partial filtration output of the old water, at this time, the waste water control valve 31 is opened, the old water control valve 41 is opened, the drain control valve 201 is opened, a part of the old water output by the pure water port 62 is guided by the old water discharge channel 4, sequentially passes through the old water control valve 41 and the second one-way valve 42 to reach the waste water output end 30, is directly discharged after being merged with the waste water, and the other part of the old water is guided by the pure water discharge channel 2, passes through the drain control valve 201, the first one-way valve 21 and the high-pressure switch 22 to reach the post-positioned filter core assembly 23 for filtration treatment, and then is output at the pure water output end 20.
Through the arrangement of the waterway system controlled by the stale water, the first cup of water restarted after the system is standby is used as stale water to be selected to be completely discharged or partially discharged and partially filtered and then output; thereby reducing the waste of water sources while ensuring the water quality requirement of water intake of users.
