However, there is a problem in the conventional water purifier
in that the plurality of filtering members arranged at the rear
wall of the boby thereof tend to deflect the rear wall toward a
rear side thereof because of the heavy weight of the plurality of
filtering members, to thereby cause an electrical malfunction or
erroneous contact between the water level detecting sensor attached
to the storage tank and connecting terminals mounted at the rear
wall thereof, so that the appropriate water level of the stored
purified water in the storage tank cannot be maintained, and worse
yet, the purified water can overflow the storage tank due to continued
supply of the purified water.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT OF THE INVENTION
The preferred embodiment of the present invention will now be described
in detail with reference to FIGS. 2 and 3.
Referring to FIGS. 2 and 3 reference numeral 10 represents a body
having an upwardly extending rear wall 10a and the body 10 releasably
carries at an upper side thereof a purified water tank 12 for storing
the purified water (W) therein.
The tank 12 is coupled at a front side thereof to a disposal outlet
16 for being opened and closed according to manipulation of a lever
14 so that disposal of the purified water (W) can be possible.
In addition, the tank 12 is provided interiorly thereof with a
plurality of water level detecting the sensors 18 for detecting
level of the purified water (W).
The rear wall 10a of the body 10 is formed with a filter support
structure in the form of a plurality of rearwardly protruding connectors
or boss units 10b, and the boss units 10b are fixed to filtering
members 22 through the medium of a brackets 20. Also the rear wall
10a is coupled to a reinforcing member 24 having an approximately
"L" shaped support portion 24a.
The reinforcing member 24 is fixedly connected at one side thereof
to the boss units 10b, and the support unit 24a is fixedly coupled
to a boss unit 26a of a base member 26 connected under the body
Meanwhile, under the filtering members 22 an inverted U-shaped
supporting unit 28 is connected to the filtering members 22 and
fixedly connected to the boss unit 26a.
In addition, an initial one of the filtering members 22 is connected
at an upper side of an outer container thereof to a water supply
pipe 30 for supplying the water, and, a final one of the filtering
members is connected at a lower side thereof to a purified water
pipe 32 for supplying the purified water (W) into an infuse hole
32a formed at the storage tank 12. One of the filtering members
is connected to a discharge pipe 34 for discharging concentrated
A back cover 36 is coupled to the rear side of the body 10 and
reference numerals 38a and 38b designate lids which cover upper
sides of the purified water tank 12 and the back cover 36 respectively,
and reference numeral 40 is a pressure pump for supplying pressure
to the supplied water.
Now, the operation of the water purifier according to the present
invention thus constructed will be described.
First of all, the water supplied through the water supply pipe
30 becomes purified when passing through the filtering members 22
and is stored in the purified water tank 12 at a predetermined level
through the purified water pipe 32 and, at the same time, the concentrated
(unfiltered) water produced at the filtering members 22 is drained
out through the discharge pipe 34.
The purified water (W) stored in the purified water tank 12 becomes
available for drinking when a disposal outlet 16 is opened by way
of the manipulation of a lever 14 and the purified water (W) in
the purified water tank 12 is maintained at the predetermined level
by the water level detecting sensor 18.
At this time, the sides of the filtering members 22 are supported
by the plurality of brackets 20 and, at the same time, their bottoms
are supported by the supporting member 28 to thereby minimize the
load of the filtering members 22 transferred to the rear wall 10a.
Even though a minimized load of the filtering members 22 is transferred
to the rear wall 10a, the rear wall 10a is not affected by the deflection
load due to the reinforcing member 24 fixedly coupled to one side
thereof, to thereby prevent deflection of the rear wall 10a.
Accordingly, electrical contact of the plurality of water level
detecting sensors 18 attached in the purified water tank 12 can
be surely maintained by non-deflection of the rear wall 10a, thereby
causing the purified water (W) to maintain an appropriate level
at all times, so that overflow of the purified water (W) resulting
from an inadequate contact of the water level detecting sensors
18 can be prevented.
As apparent from the foregoing, the water purifier according to
the present invention can minimize the load transferred by the plurality
of filtering members by way of the reinforcing member 24 and the
support member 28 to prevent deflection of the rear wall, and,
to thereby make it possible to have a sure detection of the water
level detecting sensor.
Due to this, the overflow of the purified water or erroneous operation
can be prevented, to thereby maintain an appropriate level of purified
water at all times.
Having described a specific preferred embodiment of the invention
with reference to the accompanying drawings, it is to be understood
that the invention is not limited to that precise embodiment, and
that various changes and modifications may be effected therein by
one skilled in the art without departing from the scope or spirit
of the invention as defined in the appended claims.
