In order to meet the requirement of further hot water production, a water suction pump 82 may be disposed between the pure water outlet channel 2 and the heating assembly 81.
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; and the reverse osmosis filter element assembly 6 is used for filtering, wherein the pure water is partially output from the pure water port 62, and is sequentially output to the pure water output end 20 through the first check valve 21, the high-voltage switch 22 and the post-filter element assembly 23 under the guidance of the pure water outlet flow passage 2, and the pure water at normal temperature is output.
Or the user selects the hot water output end 80 to take water, the pure water filtered by the reverse osmosis filter element assembly 6 flows to the water pump 82 under the guidance of the hot water outlet flow passage 8, and is output by the heating assembly 81 heating the rear hot water output end 80 and outputting the heated hot pure water.
Based on practical application conditions, limited by the power and heating efficiency of the heating element 81, in order to ensure stable hot water temperature output of the hot water output end 80, under the design condition that the water path system of the scheme has a large flux, through the control of the water suction pump 82 and the corresponding control valve, a part of the large amount of output pure water is guided to the hot water output end 80 through the hot water outlet flow channel 8 according to a specific flow rate and output, and the other part of the large amount of output pure water flows back to the raw water inlet flow channel 1 under the guidance of the old water return flow channel 5.
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 backflow control valve 51 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 reflux of the old water, at this time, the waste water control valve 31 is opened, the old water control valve 41 is opened, the reflux control valve 51 is opened, a part of the old water output by the pure water port 62 is guided by the old water discharge flow passage 4, passes through the old water control valve 41 and the second one-way valve 42 in sequence and is directly discharged to the waste water output end 30, the other part of the old water is guided by the old water reflux flow passage 5, is guided by the old water discharge flow passage 4, flows to return to the raw water inlet flow passage 1 through the reflux control valve 51 and the third one-way valve 52, is mixed into the water source filtered by the preposed filter element assembly 13, and is input to the reverse osmosis filter element assembly 6 through the water inlet 61 again.
Through the arrangement of the waterway system for the stale water to flow back, 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; thereby reducing the waste of water sources while ensuring the water quality requirement of water intake of users.

Specifically, the stale water diversion channel includes a first return branch 7 communicating between the pure water outlet channel 2 and the stale water return channel 5, and in a stale water treatment mode, the stale water obtained is diverted in three portions based on the arrangement of the first return branch 7, one portion of stale water is discharged to the waste water outlet 30 under the guidance of the stale water outlet channel 4, the other portion of stale water is drained to the raw water inlet channel 1 under the guidance of the stale water return channel 5 through the stale water outlet channel 4, and the other portion of stale water is drained to the raw water inlet channel 1 through the return control valve 51 and the third check valve 52 through the pure water outlet channel 2 and returned to the raw water inlet channel 1 under the guidance of the first return branch 7.
Example 3:
based on the arrangement of embodiment 1, as shown in fig. 3, in this embodiment, the old water backflow channel 5 is provided with the second backflow branch 9 in an extending manner, so that the old water output from the waterway system can be heated and then output for application, thereby being capable of adapting to different hot water output requirements of hot water application environments.
Specifically, the second return branch 9 is connected between the old water control valve 41 and the return control valve 51 at one end, and between the post-filter cartridge assembly 23 and the heating assembly 81 at the other end.
