Water-dispensing system for generating boiled water of different temperatures

A water-dispensing system for generating boiled water of different temperatures comprising:

• an inflow area including an inlet channel connected to a water source for introducing unboiled water from said water source into said inlet channel;
• a boiling area including a heater disposed on said inlet channel, a hot-water channel extending outwards from said heater, a hot-water outlet formed at one end of said hot-water channel, a first control valve disposed on said hot-water channel, and a feeding channel connected to said hot-water channel via said first control valve, said unboiled water of said water source being introduced from said inlet channel into said hot-water channel and subjected to a boiling treatment conducted by said heater whereby said unboiled water is turned into hot boiled water, said hot boiled water being exported through said hot-water outlet;
• a heat-exchange area including a heat-exchange container, a heat-exchange pipe sinuously disposed in said heat-exchange container for receiving said hot boiled water, and a cooling unit outside said heat-exchange pipe, wherein one end of said heat-exchange pipe is connected to said feeding channel, and another end of said heat-exchange pipe is connected to a warm-water channel, said cooling unit including a cooling material in the form of fluid accommodated in said heat-exchange container, said cooling material being adapted to subject said hot boiled water received by said heat-exchange pipe to a heat-exchanging treatment whereby said hot boiled water is turned into warm boiled water, said warm-water channel having a warm-water outlet adapted to export said warm boiled water, said cooling unit further including a first delivery pipe and a second delivery pipe extending outwards from said heat-exchange container respectively, thereby allowing said heat-exchange container to export said cooling material through said first delivery pipe and import said cooling material from said second delivery pipe;
• and
• a chilling area including a refrigerant container, a chilling pipe sinuously disposed in said refrigerant container and connected to said warm-water channel for receiving said warm boiled water, a cold-water channel extending outwards from said chilling pipe, a cold-water outlet formed at one end of said cold-water channel, and a chilling unit adapted to cool said warm boiled water within said refrigerant container, said refrigerant container being disposed between said first delivery pipe and said second delivery pipe, said refrigerant container thereby being adapted to receive said cooling material exported by said first delivery pipe and cool said cooling material down with said chilling unit, and said heat-exchange container being allowed to import said cooling material which is cooled down from said second delivery pipe, thereby facilitating the circulation of said cooling material between said refrigerant container and said heat-exchange container, a second control valve being disposed at a junction of said chilling pipe and said warm-water channel, said warm boiled water of said warm-water channel being allowed to flow into said chilling pipe inside said refrigerant container under the control of said second control valve, and said warm boiled water thereby being cooled down by said chilling unit and turned into cold boiled water, said cold boiled water being exported through said cold-water outlet.
