An automatic cold and hot distilled water fountain comprising a distilling chamber, a condensing mechanism, a water reservoir and a heating box;
- said distilling chamber including an upper cover and lateral draining switch to facilitate the draining and cleaning of said distilling chamber, a water incoming tube which communicates said distilling chamber with an external water source, a solenoid disposed on the incoming water tube for controlling the water coming therefrom, a manually operated switch disposed said water fountain for manually controlling said incoming water tube. A first ceramic heater and a water level controlling float disposed in said distilling chamber;
- said water level controlling float being formed by a post and a limit float mounted thereon, whereby said limit float will ascend or descend with the change of water level, so that when the water level drops down to a lower limit, an inner magnet of said limit float contacts with a lower limit electrode to produce an electrical signal which activates said solenoid, and reversely, when the water level ascends to an upper limit, said magnet contacts with an upper limit electrode to shut off said solenoid;
- said condensing mechanism including a condensing tube surrounded by multiple radiators, and a cooling fan disposed under said condensing tube for enhancing the cooling effect and speeding the condensing process of steam;
- said water reservoir being communicated by said condensing tube with said distilling chamber so as to collect distilled water formed by the condensed steam coming from said condensing tube;
- a cold water faucet mounted on the front side of the water reservoir for direct serve, an upper and a lower float wheels disposed on a lateral wall of the water reservoir, whereby when the water level of said water reservoir drops down to said lower float wheel, said first heater in said distilling chamber is activated to heat the water flowing into said distilling chamber and when the water level of said water reservoir ascends to said upper float wheel, said first heater in said distilling chamber is shut off to stop the heating process;
- and
- said heating box being disposed beside said reservoir and communicated therewith by a non-return tube which is located at a rear bottom portion of said heating box, allowing water in said reservoir to flow only in one direction from said reservoir through said non-return tube into said heating box, and, due to the atmospheric pressure, the Water level in said reservoir can be as high as that in said heating box;
- a second heater in said heating box and thermal sensor disposed in said heating box, wherein said second heater is controlled via a manually operated switch or automatically controlled in such a manner that said thermal sensor detects the temperature of the water in said heating box and produces a signal to control the turning on and off of said second heater so as to maintain the temperature of the water in said heating box at a preset value, an external hot water faucet disposed on a front side thereof for discharging hot water therein to serve a user, and an additonal connecting tube disposed on a top portion of said heating box for communicating the same with said water reservoir, whereby the steam produced in said heating box during the heating process can be fed back into said water reservoir through said connecting tube.
