Water purifier description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a water purifier, and more particularly
to a below-the-sink reverse osmosis water purifier for removing
various harmful impurities contained in the potable water.
2. Description of the Prior Art
Generally, a water purifier serves to remove various harmful materials
contained in fresh water to thereby provide purified water.
Such a water purifier is divided according to purifying method
into a natural filtering type, a direct filtering type, an ion exchange
type, a reverse osmosis type and so on. Especially, the water purifier
of the reverse osmosis type serves to apply a certain amount of
pressure to the fresh water to cause same to pass through an artificial
semipermeable membrane for water purifying. The water purifier then
isolates and removes heavy metals, bacteria, cancer-causing materials,
etc. and at the same time causes only the pure water and dissolved
oxygen to pass therethrough. The water purifier has been used in
high technology scientific or precision industries for cleansing
electronic elements or at hospitals for medical use, and in recent
years is used for providing potable water to households and shops.
A reverse osmosis water purifier, as shown in FIG. 1 comprises
a plurality of filtering members 40 which purify the fresh water
provided from a water pipe 30 connected with a faucet 20 disposed
under a sink 10 by removing impurities contained therein; a storage
tank 50 installed near the plurality of the filtering members 40
for storing purified water purified by passing sequentially through
the plurality of the filtering members 40; and a purified water
tap 70 for receiving the purified water stored in the tank 50 through
a purified water pipe 60 to thereby discharge (dispense) same at
the sink 10.
In other words, the filtering members 40 comprise a prefilter 41
a carbon filter 42 and a post filter 43 for eliminating various
impurities including rust and chloride elements contained in the
fresh water supplied from water pipe 20; a membrane filter 44 for
removing heavy metals and cancer-causing materials contained in
the fresh water and at the same time for providing the purified
water to the purified water storage tank 50; and a post-processing
filter 45 for absorbing and eliminating chloride odor and organic
Further, a concentrated water pipe 80 is disposed between the membrane
filter 44 and discharging pipe 12 in order that concentrated (waste)
water made while passing through the membrane filter 44 can be discharged
through the discharging pipe 12.
The plurality of filtering members 40 as shown in FIG. 2 and FIG.
3 are mounted by a bracket 90 formed by a steel plate bent in a
stair shape. That is, the prefilter 41 the carbon filter 42 and
a post filter 43 are respectively mounted to extend vertically at
a lower surface of a rear horizontal part 91 of the bracket 90
while the membrane filter 44 is mounted at an upper surface of the
horizontal part 91 and the post-processing filter 45 is mounted
to extend horizontally above the membrane filter 44.
Further, a vertical part 92 is integrally formed underneath the
horizontal part 91 at a right angle and a compression pump 110 is
mounted on an outer surface of the vertical part 92.
However, there is a problem with the conventional water purifier
thus constructed in that it has no outer case containing the filtering
members and is constructed with a plurality of the filtering members
40 on a rear end of the bracket 90 thereby causing a mounting area
for circuit elements (not shown) and the compression pump 110 to
be disposed in a cramped area. Also, the water purifier must be
mounted aslant in the sink 10 for the water purifier cannot be balanced
due to different gravity centers of the plurality of filtering members
Accordingly, the present invention is provided to solve the above
problems, and it is an object of the present invention to provide
a water purifier whose size is minimized and which is capable of
easy assembly and disassembly whereby an inclination thereof caused
by an unbalancing of the water filled filtering members is prevented.
SUMMARY OF THE INVENTION
The above and other objects are achieved according to the invention
by a water purifier employing a plurality of filtering members and
hoses connecting the filtering members to eliminate various impurities
contained in the fresh water, further comprising a body containing
the filtering members mounted at a certain frontal height by way
of a bracket and a compression pump, a concentrated water control
valve, a circuit board, a high voltage transformation and the like
at a predetermined rear height and having a large-bottomed area
in order to balance weight of these elements.

formed on the front side of the lower part of the vertical surface
to thereafter be coupled to the fixing rib 201b.
Now, the operation of the water purifier according to the present
invention thus constructed will be described.
When a purified water faucet 70 is turned on in order to dispense
purified water, power is applied to the compression pump 230 and,
at the same time, the fresh water (tap water) flows sequentially
through the plurality of filtering members 220 from a water supplying
pipe 30 and is purified by eliminating various harmful materials.
In other words, the fresh, incoming water flows into the sediment
filter 221 through the water supplying pipe 30 and floating materials
in the water are eliminated; then the partly purified water flows
into the pre-processing filter 222 and is discharged with harmful
materials being eliminated; now, the more purified water flows into
the compression pump 230 through the connecting hose 310 and is
forced through the membrane filter 223 with heavy metals and cancer-causing
materials being eliminated.
The purified water from the membrane filter 223 is delivered to
the purified storage tank 50 through the connecting hose 310. In
response to a control signal sent to the purified water storage
control valve 280 stored purified water from the purified water
storage tank 50 flows through the post-processing filter 224 with
bad odors and gas elements being eliminated. And the purified water
having passed through the post-processing filter 224 is guided to
the purified water faucet 70 through the purified water pipe 60
and thereafter the purified water is discharged at the sink 10 as
the faucet 70 is turned on.
At this time, the concentrated (waste) water generated in the membrane
filter 223 is guided to the rear bottom of the purifier through
the concentrated water connecting hose 320 connected to the concentrated
water discharging hole 223a formed on a lower side of the membrane
filter 223 according to control of the valve 240 and at the same
time, is discharged to the discharging pipe 12 of the sink 11 through
the concentrated water pipe 80 to thereby prevent contamination
of the membrane filter 223 caused by deposition of concentrated
water and prolong the life of the filter.
As is apparent from the foregoing, there is an advantage in the
above described water purifier of the present invention in that
it is possible to minimize a body size of a water purifier and make
easier an assembly and a disassembly of the purifier and to prevent
the purifier from tilting to one side by an unbalanced weight of
the filter members filled with water, because a plurality of the
filtering members are mounted on a front part of the body and the
electronic units are mounted at a rear part of the body to thereby
enable a bottom area thereof to be widened for balancing the weight
of the body.
