In a preferred embodiment, the pure water return channel 5 is connected between the pure water outlet channel 2 and the heating unit 91, so that the pure water return channel 5 and the hot water outlet channel 9 are arranged in parallel and communicated with each other.
The setting and function application principle of the waterway system is as follows:
firstly, in a conventional pure water making mode, a user selects the pure water output end 20 to take water, an external water source is input from the raw water input end 10, and is guided by the raw water inlet flow channel 1 to sequentially pass through the preposed filter element assembly 13, the water inlet valve 12 and the pressurizing assembly 11 and then input to the water inlet 61; 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 to take water from the hot water output end 90, then by the pure water part filtered by the reverse osmosis filter element assembly 6 is guided by the hot water outlet flow passage 9, and then the pure water outlet flow passage 2 drains the water to flow into the water suction pump 92, and then the heating assembly 91 heats the output of the rear hot water output end 90, and the output has the hot pure water after heating.
Based on practical application conditions, limited by the power and heating efficiency of the heating assembly 91, in order to ensure stable hot water temperature output of the hot water output end 90, under the design condition that the water path system of the scheme has large flux, through the control of the water suction pump 92 and a corresponding control valve, a part of the large amount of output pure water is guided to the hot water output end 90 through the hot water outlet flow channel 9 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 guide of the pure water return flow channel 5.
The wastewater generated by the reverse osmosis filter element assembly 6 is output from a wastewater port 63, and a wastewater control valve 31 is opened; when the drainage valve 81 is opened, the wastewater is guided by the wastewater drainage flow channel to be output to the outside through the wastewater control valve 31 and the drainage valve 81 to the wastewater output end 30, and when the drainage valve 81 is closed, the wastewater is guided by the wastewater backflow flow channel to flow back to the raw water inlet flow channel 1 through the wastewater control valve 31, the scale reducing connecting piece 71 and the fourth one-way valve 72, and then flows back to the reverse osmosis filter element assembly 6 through the water inlet 61 after being treated by the scale reducing connecting piece 71 and the pre-filter element assembly 13 to be input to the reverse osmosis filter element assembly 6 again for application.
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, an external water source is input to the water inlet 61 through the raw water inlet channel 1 and is filtered by the reverse osmosis filter element 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 valve 81 is opened, the old water control valve 41 is opened, the return flow control valve 51 is closed, the fourth check valve 72 has an opening pressure setting, and the generated old water and waste water are guided to the drain branch 8 to be merged and then directly discharged to the waste water output end 30.
Or the form of partial discharge and partial reflux of the old water is selected, at this time, the waste water control valve 31 is opened, the drain valve 81 is opened, the old water control valve 41 is opened, and by adjusting the flow pressure setting of the fourth one-way valve 72 and the drain valve 81, a part of old water and waste water can flow to the waste water output end 30 to be directly discharged under the guidance of the corresponding old water drainage flow channel and the waste water drainage flow channel; the other part of the old water and the waste water are guided by the corresponding old water backflow flow channel and the waste water backflow flow channel, flow back to the raw water inlet flow channel 1 through the backflow branch 7, are mixed into the water source input from the raw water input end 10, and input to the reverse osmosis filter core assembly 6 through the water inlet 61 again.
The backflow control valve 51 is opened or closed according to different application scenarios. When the backflow control valve 51 is opened, part of the old water is filtered by the post-filter element assembly 23 and then flows back, thereby further effectively performing the flushing application on the water inlet side of the reverse osmosis filter element assembly 6.
Through the arrangement of the waterway system of the front backflow of the old water, the first cup of water restarted after the system is standby is used as old water to be selected to be completely discharged or partially discharged under different application conditions; thereby reducing the waste of water sources while ensuring the water quality requirement of water intake of users.
The above is only the preferred embodiment of the present invention, and to the technical personnel in the technical field, without departing from the present invention, the embodiment can still be modified, and the corresponding modification should also be regarded as the protection scope of the present invention.
