  • the output devices 28-32 are:
  • a coffee pump drive 28 which receives a control signal from the controller 26 and operates within a range of speeds dependent on the received control signal
  • the controller 26 may operate the first valve 7 to direct water from the coffee heater block 5 to the drip tray 12 and cause the coffee pump 3 to pump water to the coffee heater block 5 until it has reached the required operating temperature.
  • FIG 3 shows a flow diagram of an example control process for the coffee machine 1 as implemented by the circuitry 100, in particular the control circuit 25.
  • the process commences at step 50, with the coffee machine 1 being powered on. Following this, the coffee machine 1 warms up the coffee hear block 5 and the steam heater block 6.
  • the PWM controller 27 may split and/or distribute the available power between the coffee heater block heater 30 and the steam heater block heater 31. For. example, 40% of the available power may be provided to the coffee heater block heater 30 and 60% to the steam heater block heater 31.
  • the coffee heater block 5 needs to be heated to a temperature of approximately 92 degrees Celsius and the steam heater block 6 heated to a temperature of approximately 165 degrees Celsius, then the uneven splitting of power between the blocks may result in the blocks reaching the required temperature at approximately the same time.
  • the splitting of power may be achieved by splitting a proportion of the available power to each heater block so that power is constantly fed to each heater block, or alternatively may be achieved by switching the available power between the heater blocks so that each block is cycled on and off with a duty cycle dependent on its share of the available power.
  • the controller 26 detects when the coffee heater block 5 and steam heater block 6 have reached the operating temperature by receiving a signal from the coffee heater block temperature sensor 23 and steam heater block temperature sensor 24. If one of the heater blocks reaches the operating temperature before the other, the controller 26 may cause the PWM controller 27 to redistribute supply of current to the heater block it to reach operating temperature, for example by sending 100% of the available power to that heater block.
  • step 52 the process proceeds to step 53 in which the controller 26 determines whether the coffee or water is on. This is indicated by a signal received from the coffee user control 20 or the water dispenser user control 22.
  • the hot water dispenser 10 and group head/handle 9 operate from the same heater block and the coffee machine 1 allows only one to be operated at a time.
  • a further heater block may be provided to allow independent operation of the group head/handle 9 and the hot water dispenser 10. This alternative embodiment may require additional power when coffee, water and steam are provided simultaneously.
  • step 54 the controller 26 determines whether steam is also required, as indicated by a signal received from the steam wand user control 21. If steam is not required, the controller 26 causes the PWM controller 27 to fully power the coffee heater block heater 30 (step 55).
  • Step 55 may involve providing less than the total available power to the coffee heater block heater 30. This may provide improved control characteristics for the coffee heater block 5, particularly if there is a lag between the actual temperature of the coffee heater block 5 and detection of the temperature by the coffee heater block temperature sensor 23. For example, if an available power supply for both heater blocks is 2,300 Watts (which result from a 2,400 Watt supply to the coffee machine 1, less about 100 Watts to drive the pumps, control circuit and other devices), the PWM controller 27 may supply approximately 1 ,200 Watts to the coffee heater block heater 30 when increasing the temperature of the coffee heater block 5, which may reduce overshoot of the target temperature than if 2,400 Watts was used.
  • the water is on all available power, in this example 2,300 Watts, may be provided to the coffee heater block heater 30, to allow increased speed and heating. Often there are less stringent requirements for the temperature for water supplied to the hot water dispenser 10 in comparison to those for the group head/handle 9, which may allow increased tolerance to overshoot.
  • Different power levels to the coffee heater block heater 30 may be used if required.
  • the selection of the appropriate power level to supply to the coffee block heater supply circuit 30 may depend on the lag in the control system. A smaller lag may allow a higher amount of power to be supplied to the coffee heater block heater 30.
  • step 54 the controller 26 determines that the steam wand user control 21 is on, the process proceeds instead to step 56 and the control circuit 25 distributes power between the coffee heater block heater 30 and the steam heater block heater 31.
  • step 56 the control circuit 25 distributes power between the coffee heater block heater 30 and the steam heater block heater 31.
  • step 57 the controller 26 controls the speed of operation of the coffee pump 3 and the speed of the steam pump 4, dependent on the temperature of the coffee heater block 5 and the steam heater block 6, as detected by the coffee heater block temperature sensor 23 and the steam heater block temperature sensor 24 respectively. For example, if one of the blocks drops below a required temperature, the respective pump may be slowed down to reduce the flow of water into that heater block. Similarly, the pump speed may be increased as the temperature of the heater block increases.
  • step 53 if the controller 26 determines that neither coffee nor water is required, the process proceeds to step 58 and the controller 26 determines whether steam is required. If not, the process cycles around steps 53 and 58 and the control circuit 25 maintains the temperature of the coffee heater block 5 and the steam heater block 6 at their respective required holding temperatures in a process similar to step 51.
  • the holding temperatures may be the same as the operating temperatures, or may be less to conserve some power while still reducing any delay before reaching the operating temperature.
  • control circuit 25 supplies full available power to the steam heater block heater to 31 (step 59). Taking the previously described example, this would result in 2,300 Watts being provided to the steam heater block heater 31.
  • the control circuit 25 then also controls the speed of operation of the steam pump 4 as required to maintain the temperature of the steam heater block 6 (step 57).
  • Switching between fully powering the heater blocks and distributing power between the heater blocks may provide increased speed of operation and may also provide improved steam generation than if power was permanently distributed between the heater blocks.
  • Providing the ability to power the coffee heater block heater 30 at two levels may provide increased control for coffee dispensing and increased speed for water dispensing.
  • the ability to distribute power to the coffee heater block 5 and steam heater block 6 may have the further advantage of allowing both to be operated simultaneously. This may be achieved by providing a lower flow rate of steam at the steam wand 11, as controlled by a reduced pump speed of the steam pump 4.
  • Figure 4 shows the flow diagram of a process that may be performed at step 56 in the process shown in Figure 3.
  • the control circuit 25 When the controller determines that coffee or water is required simultaneously with steam (as determined in steps 53 and 54 in the process shown in Figure 3), the control circuit 25 initially splits the available power between the coffee heater block heater 30 and the steam heater block heater 31 , for example in a proportion of 40% to the coffee heater block heater 30 and 60% to the steam heater block heater 31 (step 56A). This may represent the default arrangement when cycling around steps 53 and 58.
  • step 56B the control circuit 25 determines if coffee is required and the temperature of the coffee heater block 5 is low. If yes, the control circuit 25 ensues that the coffee heater block 5 is fully powered and only the remaining power is supplied to the steam heater block 6. For example, if the available power to the both heater blocks is 2,300 Watts the power to the coffee heater block 5 maybe increased from about 920 Watts, being 40% of 2,300 Watts to about 1,200 Watts.
  • the control mechanism may be linear or provide more than two levels, so that the lower the temperature drops away from the required operating temperature, the more power is supplied to the coffee heater block heater 30.
  • step 56B determines whether the coffee is on and/or the temperature of the coffee heater block 5 is low. If yes, the process proceeds to step 56E and full power is provided to the steam heater block heater 31 , at least temporarily to assist in fast heating of the steam heater block 6, at the detriment of some cooling of the coffee heater block 5. This process therefore results in a higher priority given to steam generation than to hot water generation.
  • the steam heater block heater 31 may be fully powered until the coffee heater block temperature sensor 23 indicates that the coffee heater block 5 has fallen to a certain "switch-on" temperature, which may be slightly less than the normal temperature when power would be supplied to the coffee heater block 5 for supplying water.
  • the "switch-on" temperature may be the same for when only water is being dispensed and for when both water and steam are being dispensed, but this temperature may be less than the "switch-on" temperature for the coffee heater block 5 when coffee is being dispensed.
  • the power to the steam heater block heater 31 may be increased and the power to the coffee heater block heater 30 reduced.
  • the PWM controller 27 may supply power to the heating blocks 5, 6 as shown in Table 1.
  • the power distribution may be varied to allow faster compensation.
  • the coffee heater block 5 may be given priority when the coffee machine 1 is in coffee and steam mode and the steam heater block 6 may be given priority when the coffee machine 1 is in hot water and steam mode.
  • the steam iron 200 may include user controls of hot plate temperature control 70, for setting the temperature of the hot plate and a steam control 71 for controlling the amount of steam produced. Both of these may be a dial, turned to the required setting by the user.
  • the steam iron may also include a steam blast control 72, for providing a short blast of additional steam.
  • the steam iron 200 also includes a power and switching circuit 73, which receives power from a power supply (VCC) and switches it between a hot plate heater 74 and a steam station heater 75.
  • VCC power supply
  • the power supply and switching circuit 73 receives temperature signals for the hot plate from the hot plate sensor 76 and temperature signals for the steam station from the steam station sensor 77.
  • the temperature signals may be from a thermistor, thermocouple, thermostat, pressure switch or other suitable device.
  • the hot plate heater 73 is given 'priority' over the steam station heater during most operations. Under this priority arrangement, all available power is directed to the hot plate heater 74 when it is required to bring the hot plate up to a required temperature, which depends on the setting of the hot plate temperature control 70. When the hot plate heater 74 is not in use, in other words the hot plate sensor 76 indicates that the hot plate is at its set point (allowing for any hysteresis cycle built into the power supply and switching circuit), then power is made available to the steam station heater 75 whenever it is needed.
  • This priority arrangement may optionally be reversed whenever the steam blast control 72 is operated. By reversing this arrangement a prolonged supply of steam may be available than if the steam iron did not reverse the priority arrangement.
  • T H is the current hot plate temperature
