Definitions

  • the present invention relates to an instant boiling water heater system.
  • the invention relates to an instant boiling water heater system for dispensing boiling water.
  • a further drawback common to many appliances is that as water is heated close to boiling point, the relationship between energy in to temperature rise is not linear. As water gets closers to boiling point, an increasing amount of energy is required per degree rise in temperature. The reason is that when water begins to boil, the additional energy applied converts water from a liquid phase to a gaseous phase and this is done without change to the temperature. It is only after all the liquid is converted to gas that the temperature will begin to rise. So, as water is heated close to boiling point, some of that energy is converted to small pockets of gas or vapour without any significant increase to the overall temperature, hence the bubbling that begins to occur close to boiling point.
  • a further drawback of boiling water heaters is the lime scale present in hard water areas that forms inside the boiling water storage tank and on the heating elements.
  • the formation requires regular maintenance as well as forming an insulating layer over the heating element. This insulating layer reduces the efficiency of the heating element resulting in more electrical power being required to achieve the same result as well as reducing the life of the element.
  • Some appliances pump their boiling water out of the storage tank. As the water temperature gets close to boiling point, this can cause cavitation in the pump resulting in poor flow or water delivery.
  • the second drawback is that this system normally leaves water in the tube leading from the tank to the outlet faucet. This water in the tube cools down over time to the ambient air temperature, so when the next delivery of boiling water is required; a quantity of cooled water is delivered into the cup prior to boiling water. Users who are familiar with this problem will often dispense a quantity of water to waste before the usable boiling water is delivered into the cup or pot.
  • the more sophisticated systems separate the incoming water supply from the delivery system. They usually dispense the water from the boiling tank by pumping the water out. They also only allow incoming water into the tank at the rate that the heating element can keep up with maintaining the water at an acceptable temperature. The result of such a system is that any water being dispensed will normally be close to boiling temperature. However, when the tank empties, no water will be dispensed until the tank has recovered sufficient boiling water to allow more to be dispensed.
  • the pumped system also has the advantage of allowing the water in the delivery tube from the tank to the faucet to drain back into the tank after use, thereby preventing a quantity of water in the tube to cool down. The result is that the first drop of water dispensed should be close to the desired water temperature.

  • the boiling water system 10 is located under a bench top 19.
  • the first tank 17 includes a heating element 20. This is typically an electric heating element but other suitable types of heating elements, such as gas, may be used. Furthermore, the first tank 17 includes a temperature measuring device 21 such as a thermocouple, thermistor or negative temperature coefficient thermistor (NTC). The first tank 17 also includes a dispending outlet 24 for dispensing hot water through the faucet 15.

  • the expansion tank 23 is connected to the first tank 17 via the inlet conduit 24 of the expansion tank 23.
  • the expansion tank 23 includes a venturi tube 26 located between and connecting the inlet 24 to the outlet 25 of the expansion tank 23.
  • the first tank 17 dispenses hot water through outlet conduit 25 and out through the faucet 15 via the venturi 26 and heating device 27.
  • the boiling water heater system 10 also includes a heating device 27 including a body 27a, a heating element (not shown), an inlet conduit 25 and an outlet conduit 18a.
  • the heating device 27 comprises a cast aluminium body into which a helical stainless steel passageway and a stainless steel or Incoloy heating element are cast.
  • the heating element can be made from any suitable metal. Aluminium provides an ideal metal for the body 27a of the heating device 27 due to the low specific heat (0.91 kJ/kg K) properties and low melting temperature of aluminium relative to other metals. It will be appreciated that the body can be made from any suitable material with a high thermal mass, low specific heat and low melting temperature.
  • the heating element of the heating device 27 is typically an electric heating element but may be any suitable heating element.
  • the heating device 27 also includes a temperature measuring device (not shown) such as a thermistor or NTC.

  • GPO mains general purpose outlet
  • the controller 22 can be configured to control the first heating element 20 in the first tank 17 and the second heating element in heating device 27 such that the controller directs power to an element as it is needed. As a result, each individual element could be rated up to 2400W.
  • the primary objective is to heat the water in the first tank to 80 Q C as quickly as possible and therefore a majority of the electrical power is directed to the first heating element 20 by the controller 22.
  • the heating device 27 heats up very fast so less electrical power is directed to the heating device 27 by the controller 22.
  • the controller 22 monitors the temperature of the first tank 17 and the heating device 27 until sufficient temperatures have been reached.
  • the first heating element 20 and heating device 27 only need to be occasionally supplied with electrical power to maintain their respective temperatures.
  • the controller 22 can direct, for example, 75% of the available electrical power to the heating device 27 while the remaining 25% of the electrical power is directed to the heating element 20 of the first tank 17.
  • the temperatures of the first tank 17 and the heating device 27 are constantly monitored, power can be applied to the element most in need, while at all times ensuring the total current draw is at or less than the total available power supply.

  • the indicator light 28 also indicates the status of the filtration system 13.
  • the water supplied to the system 10 is filtered through the water filtration system 13.
  • the water passing through the filter 13 to a ceramic disc cartridge passes through a water flow meter 14 to measure the volume of water used.
  • the flow control does not use any solenoid valves, but uses a standard ceramic disc cartridge commonly used in mixer taps available today.
  • this design ensures that only when the ceramic cartridge is operated can incoming water enter the system. As a result, there is a minimised risk of accidental flooding if the system is left unattended. The system therefore does not require a flood sensor.
  • the first tank 17 heats up the water via the heating element 20 to around 80 Q C for example.
  • the heating device 27 is empty of water but is heated to, for example, 120 Q C.
  • the heating device 27 acts as a heat sink or storage medium for heat to rapidly heat water that passes through the stainless steel conduit.
  • the temperature of the stainless steel water conduit also rises to the temperature of the aluminium block. This facilitates rapid boiling of the water in the system 10.
  • Activation of the faucet 15 causes cold water to flow through conduit 18b to the faucet 15 and then from the faucet 15 through conduit 18c into the first tank 17.
  • the flow of cold water into the first tank 17 causes hot water to be discharged from the first tank 17 through the outlet conduit 25 and through the venturi 26 of the expansion tank 23.
  • the hot water then passes through the venturi tube 26 located in the expansion tank 23 causing any residual hot water in the expansion chamber 23 to be drawn into the heating device 27.
  • the heating device 27 is heated and maintained at a high temperature at all times.
  • the water could also be transferred from the first tank 17 to the heating device 27 by a pump (not shown).
  • the heating element in the heating device 27 As the heating element in the heating device 27 is at a higher temperature, the water is rapidly raised to boiling point. The boiling water leaving the heating device 27 passes through the faucet 15 delivering boiling water. Once the desired volume of water has been dispensed and the ceramic cartridge is shut off, the water in the conduits from the expansion chamber 23, the heating device 27 and the conduit 18a to the faucet 15 drains back through the venturi 26 and into the expansion chamber 23 to be kept at the same temperature as the first tank 17. When the next dispensing of water is required, the water that is dispensed out of the first tank 17 passes through the venturi 26 to the heating device 27 and in so doing draws with it the water that was allowed to drain back into the expansion chamber 23.
  • the use of the expansion chamber 23 and venturi 26 prevents any water that would typically remain in the conduit 18a between the first tank 17 and the faucet 15 from boiling overly high. Further advantageously, no water remains in the conduits or faucet to cool. [0055]
  • the use of a ceramic disc cartridge eliminates the need for solenoid valves. Furthermore, the controller simply switches the heating elements on and off based on temperature sensing inputs, dispensing with the need for a boiling water calibration system.
  • the size of the system is reduced as the elimination of all valves and pumps results in a more compact system.
  • a further advantage lies in operating the first tank at a lower temperature which reduces the rate of lime scale build up on the heating element thereby increasing the heating efficiency over a longer period and extending the operating life of the heating element.
  • reducing the storage tank temperature from 98 Q C to 80 Q C can significantly reduce energy consumption resulting in lower operating costs.
  • the flow meter measures the consumption of water to determine when the filter needs changing, while also acting as an indicator for the system to activate the heating element of the heating device before the temperature of the water in the system begins to drop.
  • this design increases the boiling water capacity of the system.
  • utilising a cast aluminium block around the water pipe prevents the heated water from cooling rapidly and maintains the boiling water temperature.
