  • the boiler module 60 can provide one liter of heated water at a minimum average dispense temperature of 90°C (temperature measured in a cup or container).
  • the dispensing head 14 is located adjacent to a standard kitchen font 12 at a sink 10.
  • the dispensing head 14 includes a user input device 16 (e.g. touch pad, touch screen, display panel with conventional mechanical push buttons) to control and activate fluid valves and/or solenoid valves in the boiler module 60 and/or cooler module 30 ( FIGURES 2 , 7 , and 12 ).
  • Chilled, ambient, carbonated, and/or heated water from the boiler module 60 and/or cooler module 30 travel through piping (not shown) to the dispensing head 14 where the water is dispensed through a nozzle 18.
  • Heated water from the boiler module 60 can be used to prepare tea, coffee, and/or food requiring fast preparation (e.g. pasta or vegetables).
  • the boiler module 60 includes a housing 66 which surrounds and protects the components of the boiler module 60.
  • the housing 66 includes a baseplate 67, a removable cover 68, and/or a housing display 69 (such as a LCD display, viewing window, touch pad, touch screen, and/or user input device).
  • the boiler module 60 receives water from a water supply 20.
  • the water supply 20 has a predetermined water supply pressure, and the water enters the boiler module 60 through an inlet 62.
  • a filter unit 40 ( FIGURE 7 ) filters and/or descales the water before the water enters the boiler module 60.
  • the filter unit 40 can be placed downstream of the inlet 62.
  • Heated water exits the boiler module 60 through an outlet 64 and flows though piping to the dispensing head 14 where it is dispensed through the nozzle 18.

  • the pressure tank 80 is made from stainless steel and is designed as a pressure tank system.
  • the boiler module 60 and/or pressure tank 80 can be any suitable size or shape.

  • the boiler module 60 has minimal dimensions of: 260mm x 195mm x 355mm (width x height x depth).
  • the size and/or dimension of the boiler module 60 and/or any other component can vary.
  • the pressure tank 80 can include insulation 82 to minimize thermal heat loss. In one example, the insulation 82 is 40.0 mm thick.
  • a water pressure regulator 83 (which can be upstream or downstream of the inlet 62) to reduce the water supply pressure
  • an inlet valve 85 with an integrated check valve pressure reducing valve 87
  • a pressure relief valve 91 utilityized as a safety device
  • an outlet valve 93 to control the dispense of the water through the dispensing head 14, and/or the like.
  • the pressure reducing valve 87 reduces the water supply pressure to a range of 2.0 bar to 4.0 bar.
  • the water pressure regulator 83 controls the water pressure in the pressure tank 80 such that the operating water pressure in the pressure tank 80 and/or other components of the boiler module 60 are constant.
  • the operating water pressure in the pressure tank 80 is 1.0 bar above the water supply pressure.
  • the pressure relief valve 91 activates in case of uncontrolled pressure (i.e. the operating water pressure in the pressure tank 80 exceeds pressure limits of other components) and is set at a maximum 10.0 bar.
  • the pressure relief valve 91 activates, the pressure relief valve 91 releases water which is detected by a leak sensor 95 ( FIGURE 4 ) located on the baseplate 67 of the housing 66 which causes a controller (to be discussed further herein) to signal the heating element 71 to stop heating the water and signal the inlet valve 85 to block the inlet 62.
  • the boiler module 60 includes a control system 110 having a main controller 114 to control all components and systems of the boiler module 60, a touch pad controller (not shown) to activate and control water dispense from the dispensing head 14, and a boiler controller (not shown) to control the boiler and heating functions.
  • the control system 110 can be setup in combination with a control system and controller (not shown) of the cooler module 30 to operate together in a master control system / slave control system relationship.
  • the touch pad controller converts user inputs to input signals and relays the input signals to valves and/or solenoid valves such that water is dispensed through the dispensing head 14.
  • heated water is dispensed from the nozzle 18 of the dispensing head 14 when a dispense switch signal is activates an outlet valve 93.
  • the inlet valve 85 opens to refill the pressure tank 80 to maintain a constant water level in the pressure tank 80.
  • the control system 110 can include several boiler module control features. Examples of boiler module control features are listed below:
  • the heating element performance can be limited to a range of 50% to 80% of the nominal load.
  • Sleep Mode Function At 70°C or lower to reduce the energy consumption over night. Sleep mode is activated if there is no dispense for a certain time (the time can be selected for example 2hrs). To wake up the boiler module 60 the hot water dispense button needs to be selected and the heating element 71 will start to heat the pressure tank 80 until the defined temperature has been reached.
  • Heater Jump Start Function Every time a hot dispense button is selected the heating element 71 is switched on to avoid a delay. After the dispense buttons is released the heating element 71 continues to work in the normal temperature control mode.
  • the heating element 71 communicates with the dispensing head 14 and indicate readiness, or failures (e.g. "not ready” means the hot water is not hot enough to dispense (i.e. hot water ⁇ 90°C)), out of function, filter full), and option for GPRS communication for submitting the technical performance data.
  • Filter Lifetime Control can be selected by operating time or by throughput calculated by the valve opening time.
  • the usual setting is 6 months or 5000 liters throughput whatever appears first.
  • the standard flowrate is 21/min at the nozzle 18 which leads to a filter life time of 2500min or 41.66hrs valve opening time.
  • Safety Function maximum dispense is only allowed for the max portion size of 11.
  • Scale Detection System is used to detect if calcium deposits have settled on the heating element.
  • the boiler controller When heating up from sleep mode, the boiler controller will measure the temperature rise per time interval (dT/dt).
  • the default descaling interval will be 1 year. This default interval will be adjusted based on the described dT/dt measurement in the range of 0.5 to 1.2 years. If the sleep mode is never entered, the default descaling interval of 1 year will be used.
  • the scale detection system is used to give an early warning to the operator to indicate a possible problem with the heating element 71. To protect the heating element 71 a descaling service needs to be done to secure the heating element useful life.
  • the boiler module 60 can be set into an automatic sanitation mode where the filter unit 40 is replaced by a sanitation cartridge.
  • the control system activates the sanitation mode, controls the reaction time of the chemicals, and controls the flush time after sanitation. During this process the dispensing head 14 is deactivated.
  • the controller 114 is programmable and includes a processor 115 and a memory 116.
  • the controller 114 can be located anywhere in the control system 110 and/or located remote from the control system 110 and can communicate with various components of the dispensing head 14, cooler module 30, and/or boiler module 60, via wired and/or wireless communication links 111, as will be explained further herein below.
  • the controller 114 can have one or more control sections or control units.

  • movement software directs the processing system to operate the heating element 71 described herein to execute heating of water in the pressure tank 80.
  • the computing system may include one or many application modules or control features and one or more processors, which may be communicatively connected.
  • the processing system may comprise a microprocessor (e.g., processor) and other circuitry that retrieves and executes software from the storage system.
  • Processing system can be implemented within a single processing device but can also be distributed across multiple processing devices or sub-systems that cooperate in existing program instructions.
  • Non-limiting examples of the processing system include general purpose central processing units, applications specific processors, and logic devices.
  • the storage system can comprise any storage media readable by the processing system and capable of storing software.
  • the storage system can include volatile and non-volatile, removable and non-removable media implemented in any method or technology for storage of information, such as computer readable instructions, data structures, program modules, or other data.
