The invention provides a passive
water saving and purifying
system for making
purified water, and belongs to the technical field of water purifying and
water saving, and mainly solves the problem thatin the prior art, a massive waste is caused by active
purified water making and
sewage discharge. The passive
water saving and purifying
system comprises a prefilter, an ultra-
filtration water purifier, a
reverse osmosis water purifier, a
water heater, an instant direct drinking
machine and a
toilet. The passive water saving and purifying
system is characterized in that an ultra-
filtration drainoutlet of the ultra-
filtration water purifier is communicated with a water tank of the
toilet; an ultra-filtration water outlet is communicated with a kitchen cold water interface, the input end of the
water heater, a face washing basin, a cold water interface of a
shower, a cold water interface of a washing
machine and a water inlet of the
reverse osmosis water purifier; a hot water output end ofthe
water heater is communicated with a kitchen hot water interface, a face washing basin, a hot water interface of the
shower and a hot water interface of the washing
machine; a
reverse osmosis concentrated water outlet of the reverse
osmosis water purifier is communicated with an emergency concentrated water reverse
osmosis drain outlet; and a reverse
osmosis purified water outlet of the reverse osmosis water purifier is respectively communicated with a purified
water storage tank, the instant direct drinking machine and a kitchen direct drinking water interface.
