Definitions

  • Exemplary embodiments relate to devices and methods for heating liquid (preferably water) within a cooler that do not require a separate hot water tank.
  • a preferred exemplary embodiment comprises a heating tube that is wrapped with at least one heating element wherein the heating tube is connected to a water reservoir within a water cooler such that cool or room temperature water may be drawn from the reservoir and into the tube where the water is heated to a desired temperature by the heating elements as the water flows through the tube before ultimately being dispensed by the water cooler.
  • the hot water tank is controlled by a thermostat that is in thermal contact with the tank wall or water contained in the tank. When the temperature falls below a predetermined set point, the thermostat turns on the heating element of the tank and heats the water until the temperature is at the high end of the target range.
  • Heating elements used by the known tank are typically inside the tank exposed to the water or wrapped around the exterior of the tank wall. The heater wattages expended to heat the water in the tank are frequently between 400 and 500 Watts.
  • Another set-back to the known systems of providing heated water to a water cooler is that when water within the hot water tank heats up, it expands. In a water cooler, this heated expansion water flows back into the storage area that is located at the top of the cold water tank. This causes the chilled water in the cooler to warm up which in turn causes the cooling system (which is typically compression-driven) to turn on and cool the water.
  • the hot water tank system wastes energy to maintain hot water when the cooler is not in use and it causes the cooling system to cycle more frequently than is necessary to maintain cold water.
  • a preferred exemplary embodiment uses a tube or a series of tubes wrapped with heating elements, such as a thick-film printed heating element, to heat water as it is being dispensed from a cooler.
  • the flow of the water out of the tank/water reservoir which provides water to the tubing is maintained slow enough and the wattage of the heating elements is high enough that water entering the tube or series of tubes at room temperature will be heated to a temperature of between 180 and 200 degrees Fahrenheit.
  • a benefit of this system when used in a water cooler is that energy is not wasted maintaining the water at an elevated temperature.
  • Another benefit is the elimination of expansion water that causes the cold water in the cooler's water reservoir to be warmed and the corresponding cycling of the cooling system.
  • some exemplary embodiments permit for the user of the water cooler to choose the temperature of the hot water being dispensed.
  • Such embodiments preferably incorporate a microcontroller that measures the temperature of the water at or near the hot water outlet of the cooler and adjusts the flow rate of water through the heating tube/tubes (i.e. a slower flow rate for hotter water and a faster flow rate for cooler water) in order to provide the user with hot water of the selected temperature.
  • Preferred exemplary systems additionally comprise an electrical push button or switch that is pushed or switched by the user of the water cooler when it is desired that hot water be dispensed. Pushing the electrical push button or switching the switch activates the water heater and a pump/valve within the cooler that allows water to begin to flow through the heating tube/tubes.
