Water dispenser

Abstract

A water dispenser including a water inlet system, a drinking water storage system, a heat-exchange water system, a refrigeration system, a heating system and a water outlet system is provided. The drinking water storage system connects the water inlet system. The refrigeration system connects the drinking water storage system and has a water cooling tank and a first thermoelectric element. The cooling side of the first thermoelectric element contacts the water cooling tank. The heating system connected the drinking water storage system has a low-temperature water heating tank and a second thermoelectric element. A heating side of the second thermoelectric element contacts the low-temperature water heating tank. The heat-exchange system connects the water inlet system, a heating side of the first thermoelectric element and a cooling side of the second thermoelectric element. The water outlet system connects the refrigeration system and the heating system.

         2 . The water dispenser as claimed in  claim 1  further comprising a water purification system connecting between the water inlet system and the drinking water storage system. 
     
     
         3 . The water dispenser as claimed in  claim 2 , wherein the water purification system is a reverse osmosis system. 
     
     
         4 . The water dispenser as claimed in  claim 2 , wherein the water inlet system has a raw water inlet connecting the water purification system. 
     
     
         5 . The water dispenser as claimed in  claim 1 , wherein the water inlet system has a drainage outlet connecting the heat-exchange water system. 
     
     
         6 . The water dispenser as claimed in  claim 1 , wherein the water inlet system has a pure water inlet connecting the drinking water storage system. 
     
     
         7 . The water dispenser as claimed in  claim 1 , wherein the water outlet system has a cold water control valve connecting the water cooling tank. 
     
     
         8 . The water dispenser as claimed in  claim 1 , wherein the drinking water storage system compartmentally connecting the water cooling tank by an integral orifice plate. 
     
     
         9 . The water dispenser as claimed in  claim 1 , wherein the water outlet system has a hot water control valve connecting the low-temperature water heating tank. 
     
     
         10 . The water dispenser as claimed in  claim 1 , wherein the heating system further includes a high-temperature water heating tank and an immersion-type electrical heater; the high-temperature water heating tank connects the low-temperature water heating tank and the immersion-type electrical heater is disposed in the high-temperature water heating tank. 
     
     
         11 . The water dispenser as claimed in  claim 10 , wherein the heating system further has a pressure equalizing pipe connecting the low-temperature water heating tank and the high-temperature water heating tank, and the low-temperature water heating tank having a pressure relief valve. 
     
     
         12 . The water dispenser as claimed in  claim 1 , wherein the low-temperature water heating tank has a pressure relief valve. 
     
     
         13 . The water dispenser as claimed in  claim 1 , wherein the water outlet system has a warm water control valve connecting the drinking water storage system. 
     
     
         14 . The water dispenser as claimed in  claim 1 , wherein the first thermoelectric element comprises:
 a base plate having a first surface and a second surface in relative; the second surface has first flow interference channels;   at least one thermoelectric chip installed on the first surface of the base plate;   a cover plate assembled onto the second surface of the base plate, the surface of the cover plate that faces the second surface of the base plate having second flow interference channels, and the cover plate also having a water inlet and a water outlet connecting the heat-exchange water system; and   a seal ring installed between the cover plate and the base plate.   
     
     
         15 . The water dispenser as claimed in  claim 1 , wherein the second thermoelectric element comprises:
 a base plate having a first surface and a second surface in relative; the second surface has first flow interference channels;   at least one thermoelectric chip installed on the first surface of the base plate;   a cover plate assembled onto the second surface of the base plate, the surface of the cover plate that faces the second surface of the base plate having second flow interference channels, and the cover plate also having a water inlet and a water outlet connecting the heat-exchange water system; and   a seal ring installed between the cover plate and the base plate.
