water pipe 31 is continuously provided to a bottom position of the
warm water container 110 and the purified water which flows through
the second purified pipe 32 is also continuously provided to a top
position of the cold water container 120.
When the water is filled in the warm water and the cold water containers
110120 an operation of the pressurizing pump 100 is stopped upon
receipt of sensing signals from a water level protecting sensor
(not shown). That is, the water level protecting sensor is adjusted
and controlled by the level of the water to prevent the water in
the warm water and the cold water containers 110120 from overflowing.
When the heater member 111 disposed in the warm water container
110 for providing the warm water is operated, the water is heated
to a predetermined temperature. When the compressor 50 is operated
to supply the cold water, vaporous refrigerant gas in a high temperature
and high pressure state is provided to condenser 60. Also, the refrigerant
gas which flows in an inner part of the condenser 60 is condensed
by an air blast according to an operation of the cooling means 70.
At this time, the condensed vaporous refrigerant gas having passed
through the condenser 60 is turned into gaseous refrigerant having
a higher temperature than room temperature which is an amibient
temperature of the cold and warm water purification device. The
pressure of the refrigerant gas is decreased in pressure in passing
through a capillary tube (not shown). The refrigerant gas is expanded
by the cooling coil 121 wound around a circumference of the cold
water container 120 so that the water in the cold water container
120 is cooled.
If a user wants to dispense the warm water or the cold water contained
in the warm water and the cold water containers 110120 he or she
pushes an extracting lever 136 with a container (for example, a
cup). When the extracting levers 136 are pushed backward, channels
of respective extracting valves 130131 are opened. When the extracting
valves 130131 are opened, the warm and the cold water in the warm
water and the cold water containers are dispensed, respectively.
In the conventional warm and cold water purifier, a cover plate
17 disposed underneath the water retaining means 16 of the front
panel is closely connected to front edges of side panel 13 and is
fastened by a plurality of engaging screws (not shown). Thus, it
is time consuming to open and close the front panel 17 and there
is a risk of the screws becoming worn.
