Tray drawn along axis type assembly 12 is connected with the vertical fixing plate 13 for installing ultra-filtration element and reverse osmosis filter element, vertical fixing plate 13 just facing to panel 11, the inwall of the back side of vertical fixing plate 13 and cabinet 10 forms accommodation space 14, and ultra-filtration element is installed on this accommodation space 14 from rinse-system.Tray drawn along axis type assembly 12 pull-out, when rinse-system is installed, can be hung on cabinet 10, to vacate bigger space, make installation easy to operate by ultra-filtration element.
The household water-purifying machine that this utility model provides also can arrange water-saving circulating system in cabinet 10.Fig. 9 is the schematic diagram of the water-saving circulating system first embodiment that this utility model provides, and this water-saving circulating system includes reverse osmosis filter element or nanofiltration filter element 1104, reverse osmosis filter element or nanofiltration filter element 1104 and connects water inlet pipe d, water producing pipe e and dense water pipe f.This water-saving circulating system connects from rinse-system with above-mentioned ultra-filtration element, pure water pipe b connects with water inlet pipe d, water inlet pipe d is provided with preposition activated charcoal filter element 1102, feed water by reverse osmosis water quality sensor 1601 and booster pump 1103, and the water inlet pipe d in raw water tubes a or water-saving circulating system is additionally provided with low pressure sensor 1201.Waste pipe c crosses with dense water pipe f and connects, and waste pipe c is provided with ultra-filtration element flushing valve 1501 before crossing, and dense water pipe f is provided with reverse osmosis filter element flushing valve 1503 before crossing.The water producing pipe e of water-saving circulating system is connected with drinking water interface.It is provided with return duct g between dense water pipe f and water inlet pipe d, return duct g is provided with backflow waste water ratio valve 1701 and the first check valve 1301.Water producing pipe e is provided with the second check valve 1302, reverse osmosis produced water water monitor 1602, high pressure sensor 1205 and rearmounted filter core 1105, one or more series connection in activated carbon, rearmounted Maifanitum, UV lamp of rearmounted filter core.Wherein low pressure sensor 1201, high pressure sensor 1205, feed water by reverse osmosis water quality sensor 1601, reverse osmosis produced water water monitor 1602, booster pump 1103, backflow waste water ratio valve the 1701, first check valve the 1301, second check valve 1302, ultra-filtration element flushing valve 1501 and reverse osmosis filter element flushing valve 1503 are connected with control circuit signal respectively.
When feed water by reverse osmosis water quality sensor 1601 shows water quality conformance with standard, close ultra-filtration element flushing valve 1501 and reverse osmosis filter element flushing valve 1503, open water saving circulating pattern: former water flows through the scrubbing water after hyperfiltration membrane assembly 1101 filters and flows out from pure water pipe b, pure water pipe b connects water inlet pipe d, water inlet pipe d is sequentially provided with preposition activated charcoal filter element 1102 along water (flow) direction, feed water by reverse osmosis water quality sensor 1601, booster pump 1103 and reverse osmosis filter element or nanofiltration filter element 1104, the waste water of reverse osmosis filter element or nanofiltration filter element 1104 output flows out from dense water pipe f, reflux again through return duct g, sequentially pass through backflow waste water ratio valve 1701, first check valve 1301, the waste water room of hyperfiltration membrane assembly 1101 is entered again from waste pipe, again filter.The scrubbing water of reverse osmosis filter element or nanofiltration filter element 1104 output flows out from water producing pipe e, sequentially passes through the second check valve 1302, thoroughly produces water water monitor 1602, high pressure sensor 1205 and rearmounted filter core 1105, and rearmounted filter core 1105 connects drinking water interface.
The effect of low pressure sensor 1201 is protection booster pump 1103; when the hydraulic pressure that low pressure sensor 1201 detects raw water tubes is too low, booster pump 1103 does not start, it is to avoid booster pump 1103 occurs sky to take out; damage booster pump 1103, and the overheated and danger that produces when sky is taken out.Certainly this low pressure sensor 1201 can also be arranged on water inlet pipe d or running water pipe.
The effect of high pressure sensor 1205 determines that whether system is with water, when the hydraulic pressure that high pressure sensor 1205 detects water producing pipe is too high, and system-down.Certainly this high pressure sensor 1205 can be arranged at any position between the second check valve 1302 and drinking water interface.
Low pressure sensor 1201 and high pressure sensor 1205 utilizable flow sensor are replaced, it is possible to use simultaneously.
When feed water by reverse osmosis water quality sensor 1601 shows that water quality is poor, opening ultra-filtration element flushing valve 1501 and reverse osmosis filter element flushing valve 1503, the dense water of reverse osmosis filter element or nanofiltration filter element 1104 generation will not be back to ultrafiltration filter membrane component 1101.
Figure 10 is the schematic diagram of water-saving circulating system the second embodiment that this utility model provides, water-saving circulating system in the present embodiment adds four control valves and a drain pipe h on the basis of first embodiment, particularly as follows: the water inlet control valve 1502 arranged on water inlet pipe d, the recycle control valve 1505 arranged on return duct g, drain pipe h and dense water pipe f crossed before reverse osmosis filter element flushing valve 1503 and connects, and is provided with waste discharge and controls valve 1504 than valve 1702 and concentrated water discharge on drain pipe h.
This utility model provide household water-purifying machine reach to determine waste discharge amount according to water quality by water-saving circulating system, allow water purifier intelligence water saving.
