The present invention is not limited to the specific material and structure of the filter element of the post-filter device 16, and for example, the filter element may be an activated carbon filter element or a composite filter element composed of an activated carbon filter element and ultrafiltration.
The general working principle of the first embodiment is described below.
When the purifier makes water, raw water solenoid valve 11 opens, and first clean solenoid valve 32, the clean solenoid valve 41 of second, first drainage solenoid valve 22 and the second drainage solenoid valve 23 close, and first solenoid valve 13 opens, and booster pump 14 launches, and the raw water is just filtered through leading filter equipment 12 and is formed the water purification, and the water purification forms two flow paths, and a flow path is: the microbubble electrolysis module 31 entering the first clean water path 30 from the clean inlet 301 performs electrolysis of water, micro-bubble water generated by electrolysis flows into the bubble water path 50, and when the bubble water control valve is opened, the micro-bubble water flows out from the bubble water outlet 501 and is supplied to a user; the other flow path is: the pure water flows into the booster pump 14 from the pure water path 10, after the booster pump 14 boosts the pure water, the pure water enters the reverse osmosis filter 15 from the water inlet of the reverse osmosis filter 15 to be filtered for the second time, the generated concentrated water flows into the main wastewater path 201 and is discharged from the wastewater outlet 2011, the generated pure water is filtered for the third time by the post-filter 16, and under the condition that the pure water control valve is opened, more pure water flows out from the pure water outlet 102 to be drunk by users.
When the water purifier performs water path cleaning, the raw water electromagnetic valve 11 is opened, the first cleaning electromagnetic valve 32, the second cleaning electromagnetic valve 41, the first drainage electromagnetic valve 22 and the second drainage electromagnetic valve 23 are opened, the first electromagnetic valve 13, the bubble water control valve and the pure water control valve are closed, the booster pump 14 is not started, raw water is primarily filtered by the pre-filter device 12 to form purified water, the purified water enters the microbubble electrolysis module 31 of the first cleaning water path 30 from the cleaning inlet 301 for electrolysis, the microbubble water generated by electrolysis is divided into two flow paths, and one flow path is: flows into the booster pump 14 and the reverse osmosis filter 15 through the cleaning outlet 302, wherein the flow distribution of the two is set by the second drain solenoid valve 23, the reverse osmosis membranes on the water inlet sides of the booster pump 14 and the reverse osmosis filter 15 are sterilized and cleaned, and the cleaned water flows through the second drain branch 203 and the waste water port of the reverse osmosis filter 15, respectively, and is then discharged through the waste water outlet 2011. The other flow path is: flows into the reverse osmosis filter device 15 and the post-filter device 16 through the second clean water path 40, cleans the reverse osmosis membrane on the pure water side of the reverse osmosis filter device 15 and the filter element of the post-filter device 16, and discharges the cleaned water through the first discharge branch 202 and the waste water outlet 2011.

Namely: the clean outlet 302 is provided on the pure water path 10 between the first electromagnetic valve 13 and the booster pump 14.
The operating principle differs from that of the first embodiment in that: the two flow paths for the micro-bubble water exiting the clean outlet 302 are: the micro bubble water which flows out from the booster pump 14 continues to flow to the reverse osmosis filtering device 15, so that the positions of the first electromagnetic valve 13 can be cleaned, and the booster pump 14, the reverse osmosis membrane at the water inlet side and the related pipelines can be cleaned.
In addition, the principles and functions of the second clean water path 40, the bubble water path 50, and the remaining water discharge branches are the same as those of the first embodiment, and are not described again.
Third embodiment:
the clean inlet 301 is communicated with the pure water waterway 10 between the pre-filtering device 12 and the booster pump 14; the clean outlet 302 is communicated with the pure water waterway 10 between the raw water inlet 101 and the pre-filter 12; a check valve 33 is arranged on the first clean water path 30 between the water outlet end of the microbubble electrolysis module 31 and the clean outlet 302.
The setting mode has the advantages that: the micro-bubble water directly flows back to the pure water waterway 10 at the front side of the front filtering device 12, and can sterilize or inhibit bacteria and the like for the front filtering device 12 and pipelines and devices flowing through at the rear side.
Further, the waterway system further includes a bubble water waterway 50, the bubble water waterway 50 includes a bubble water inlet and a bubble water outlet 501, the bubble water inlet is communicated with the water outlet of the microbubble electrolysis module 31, and the bubble water outlet 501 is provided with a bubble water control valve (not shown in the figure).
The setting mode has the advantages that: the micro-bubble water generated by the first cleaning water path 30 can be discharged through the bubble water path 50 for the life of the user, for example, the user can directly use the micro-bubble water to sterilize fruits, vegetables, tableware and the like without using a detergent, the problem of detergent washing residue is avoided, and the water safety is ensured. In addition, the water dispenser has the functions of drinking pure water and using life water of micro-bubble water, realizes multiple purposes by one machine and improves the use convenience of users. In addition, because the bubble water waterway 50 can be sterilized in the process of making water, the risk of exceeding the standard of bacteria in the bubble water waterway 50 is greatly reduced.
Further, a water storage tank 34 is disposed on the first cleaning waterway 30 between the first cleaning solenoid valve 32 and the cleaning outlet 302, and a vent 341 is disposed on the water storage tank 34.
After micro-bubble water or pure water making is completed, the bubble water control valve and the pure water control valve are closed, when the raw water electromagnetic valve 11 is opened, the process of water electrolysis still exists in the micro-bubble electrolysis module 31 on the first clean water path 30, at this time, the first clean electromagnetic valve 32 is opened, the generated micro-bubble water is stored in the water storage tank 34, so as to sterilize and clean the water path system, wherein, the air holes 341 are arranged, the water path system can be prevented from being in a relatively closed state, so that the water pressure is insufficient, and further, the water can not be pressed to the water storage tank 34 and can not flow normally in the water path. It can be understood that the water can be prevented from being sprayed out of the air holes 341 by adjusting the opening degree of the first cleaning solenoid valve 32, i.e., controlling the flow rate of the water entering the water storage tank 34. The micro bubble water in the water storage tank 34 has a certain storage time after electrolysis is completed in the water storage tank 34 under a preset water flow, and the water path cleaning mode can be intermittent water electrolysis, for example, after the micro bubble water with a first preset water flow is stored in the water storage tank 34, the water path cleaning is started, at this time, the micro bubble electrolysis module 31 stops water electrolysis, and turns off the first cleaning electromagnetic valve 32, and when the water flow in the water storage tank 34 is a second preset water flow (smaller than the first preset water flow), the water electrolysis is performed again and the first cleaning electromagnetic valve 32 is opened, and the above steps are repeated until cleaning is completed. Although the microbubble electrolysis module 31 is described above as stopping electrolysis when performing the water channel cleaning, other control methods may be flexibly adopted when the present invention is actually controlled, for example, the microbubble electrolysis module 31 may be always in the electrolysis state when performing the water channel cleaning.
