of operation and for emitting red color during an abnormalcy state
Furthermore, the body 10 provided at a rear side thereof with a
rear wall 10c, which supports filtering means 18 including a pre-processing
filter 18a, a membrane section 18b and a post-processing filter
The rear wall 10c is provided at a lower side thereof with a water
drop infuse prevention jaw 10d.
Meanwhile, the body 10 is coupled at a lower side thereof with
a base member 20 formed with an insertion groove 20a for receiving
a lower side of the holder member 14 and the base member 20 supports
a pressure pump 22 for applying pressure to the water supplied from
the membrane section 18b.
The base member 20 facing the water drop infuse prevention jaw
10d is provided at an upper side thereof with a protruding wall
20b for preventing penetration into the chamber of 10a of moisture
from dropped water, purified water and the like.
The body 10 is coupled at a rear surface thereof with a back cover
24 and is releasably fitted at an upper side thereof to a purified
water tank 28 for storing the purified water separated from various
harmful materials included in the water which has passed through
the filtering means 18.
The purified water tank 28 is connected at a front surface thereof
with a disposal outlet 32 for discharging the purified water in
the purified water tank 28 by way of manipulation of a lever 30.
Furthermore, the purified water tank 28 and the back cover 24 are
provided at upper sides thereof with lid plates 34a and 34b respectively.
The filtering means 18 is so constructed as to be connected to a
water supply pipe 38 coupled to a faucet 36 so that water supply
can be made possible.
Numeral 40a in the drawings represents a purified water pipe for
supplying the purified water from the filtering means 18 into the
purified water tank 28.
Reference numeral 40b is a discharge pipe for discharging concentrated
unfiltered water produced at the filtering means 18.
Now, the operation of the water purifier thus constructed according
to the present invention will be described.
First of all, the water supplied from the faucet 36 to the filtering
means 18 through the water supply pipe 38 passes through the pre-processing
filter 18a, the membrane section 18b and the post-processing filter
18c to be separated from various harmful materials contained in
the water and to be infused into the purified water tank 28 to thereby
maintain a predetermined appropriate level. The concentrated unfiltered
water generated at the membrane section 18b is discharged outside
of the body 10 through the discharge pipe 40b.
At this time, the water supplied to the membrane section 18b serves
to perform a water purifying operation by way of reverse osmotic
pressure caused by pressure according to operation of the pressure
pump 22 and the purified water stored in the purified water tank
28 is dispensed by way of manipulation of the lever 32 through the
disposal outlet 32.
The filtering means 18 should be replaced after a certain period
of time of use and at that time, the plurality of display lamps
which emit green lights at normalcy serve to emit red lights for
notifying of the need for replacement of the filtering means 18.
Meanwhile, an assembly sequence of the circuit substrate 12 employing
the display lamps 12a is done in such way that, an upper portion
of the holder member 14 to which the circuit substrate 12 is coupled
is inserted to the boss unit 10b and is fastened by the bolt, and
a lower end of the holder member 14 is inserted into the insertion
groove 20a formed at the base member 20 which in turn is assembled
to a lower side of the body, thus completing the assembly of the
circuit substrate 12.
At this time, it is preferable that the holder member 14 inserted
into the boss unit 10b should be flexible so that the plurality
of display lamps 12a equipped at one side of the circuit substrate
12 can protrude through holes formed in a vertical front wall of
the body 10.
Furthermore, the circuit substrate 12 vertically provided in the
accommodation chamber 10a formed in the body 10 is not susceptible
to mishaps such as electrical leakage, short circuit and the like
because the water drop infusion prevention jaw 10d and the protruding
wall 20b prevent the infuse of water dripping from the filtering
means 18 or purified water pipe 40a into the accommodation chamber
Is apparent from the foregoing, the water purifier according to
the present invention is provided with a plurality of display lamps
for notifying in advance the need for replacement of the filtering
means to thereby enable replacement of the filtering means at an
appropriate time, and the circuit substrate equipped with the display
lamps can be easily assembled and disassembled for increase of manufacturing
productivity thereof, and more particularly, electrical accidents
such as electrical leakage, short-circuit and the like can be prevented
in advance by preventing penetration of humidity from the outside.
