  • Several different embodiments are described herein for purposes of illustration. However, these illustrative embodiments should not be used to narrowly interpret the scope of the invention.
  • a beverage forming apparatus includes a water storage tank and a metering chamber, from which liquid is provided to a brew chamber.
  • aspects of the invention are not limited to this type of arrangement.
  • aspects of the invention may be used in systems including no metering chamber, e.g., water is supplied directly from a storage tank to a brew chamber, and/or in systems having no brew chamber, e.g., systems in which a beverage is formed without brewing.
  • no metering chamber e.g., water is supplied directly from a storage tank to a brew chamber
  • systems having no brew chamber e.g., systems in which a beverage is formed without brewing.
  • various aspects of the invention are described herein, and these various aspects may be used in any suitable combination with each other, or alone.
  • a beverage forming system controller may control a pump, such as a water pump, to operate based on an operation index associated with the pump.
  • the operation index may represent an ability of the pump to deliver a particular volume flow rate, and thus the ability of the pump to deliver a specific volume of liquid over a corresponding pump operation time.
  • an “operation time” may be any suitable measure for a duration of operation for the pump, including a period of time, a number of pump cycles (e.g., shaft revolutions or strokes), a total power delivered to the pump, an integrated voltage applied to the pump, or other measure by which a duration that the pump is operated may be based.
  • the operation index may be adjustable, e.g., to allow the controller to set the operation index for the pump at an initial start up and/or at some time after the pump has been put into service.
  • the operation index may allow the controller to control the operation of the pump so that it delivers a predetermined volume of liquid even if the pump's performance characteristics (such as a nominal volume flow rate or supplied voltage) changes over time.
  • the operation index may allow the controller to accommodate pump-to-pump variation that may exist, e.g., when a pump is replaced in a beverage forming system or as between pumps in two different systems that include a same control arrangement.
  • pump-to-pump variation may exist, e.g., when a pump is replaced in a beverage forming system or as between pumps in two different systems that include a same control arrangement.
  • pumps may have the same design, specifications and be made by the same manufacturer, performance of different pump units of the same model may vary widely, in one case up to a 20% variation.
  • one pump provided in one beverage forming apparatus may operate differently from another pump in another beverage forming apparatus.
  • one pump may provide a volume flow rate that is different from another pump, even though the power supply, water supply and other operation parameters are the same.
  • the controllers in different systems may be otherwise configured in nearly identical ways, yet the controller in one beverage forming system may use a first operation index for the pump in its system, whereas the controller in another system may use a second operation index for the other pump.
  • the controller in one beverage forming system may use a first operation index for the pump in its system
  • the controller in another system may use a second operation index for the other pump.
  • the controller may operate the pump for a specific operation time so that the pump provides a desired total volume, e.g., for forming a beverage. If the pumps in two different systems perform differently, the pumps will provide different total volumes of liquid if they are both run for a same operation time. As discussed above, volume control can be important in forming beverages, e.g., to provide consistency, quality taste or appearance, or other beverage characteristics.
  • the operation index may take variations in pump performance into account and allow each controller to control its respective pump, e.g., determine an operation time for the pump, so that the pump delivers the same required volume in both systems.
  • a controller may use a power supply characteristic of power supplied to the pump to determine an appropriate operation time for the pump. For example, even if two pumps in two different beverage forming systems otherwise perform identically, if the two pumps are provided with different power voltages during operation, the pumps will typically provide different volume flow rates, in one exemplary case representing up to an 80% variation. Thus, the controller may take a power supply characteristic, such as a voltage of power to be supplied to the pump during operation, into account so that the pump can be controlled to accurately provide the desired volume of liquid.
  • a controller in a beverage forming system may use both an operation index and a power supply characteristic to determine an operation time for a pump.
  • the controller may be capable of accurately controlling the pump, even in the case of pump performance and/or power supply variations. For example, the controller may determine an operation time for the pump based on the operation index, and then make adjustments to the time during pump operation based on the voltage supplied to the pump.
  • a controller in a beverage forming system may control the pump to operate during a calibration period, and based on the performance characteristics of the pump determine an operation index for the pump. For example, at the time a beverage forming system is first operated, the controller may cause the pump to operate to provide a specific volume of liquid, e.g., to fill a chamber in the system. The controller may determine a calibration time that corresponds to a time taken for the pump to provide the volume of liquid. Based on the calibration time (which may effectively represent a volume flow rate for the pump during the calibration period), the controller may assign an operation index to the pump. Thus, the operation index may represent the pump's ability to provide a volume flow rate.
  • the operation index may be used by the controller to subsequently control the pump when delivering the specific volume delivered by the pump during the calibration period and/or for other volumes. For example, during subsequent operation of the pump to deliver a predetermined volume, the controller may determine an operation time for the pump to operate to provide the predetermined volume. The pump may then be operated for the operation time, and stopped.
  • the controller may also take a power supply characteristic of power provided to the pump during the calibration period into account when determining the operation index. For example, the controller may determine a voltage for power supplied to the pump during the calibration period and use that voltage, together with the calibration time, to determine the operation index for the pump. Subsequently, the controller may use a voltage supplied to the pump with the operation index to determine an operation time for the pump. Such an approach may be useful in applications where the voltage provided to the pump varies, e.g., because of operation of other parts of the system, such as a water heater, or variations in line voltage provided to the system, such as variations caused by the operation of devices in the electrical grid to which the system is connected.

  • Water or other liquid from a tank 2 may be provided by a water pump 52 to a metering tank or chamber 53 .
  • Operation of the water pump 52 and other components of the system 1 may be controlled by a controller 51 , e.g., including a programmed processor and/or other data processing device along with suitable software or other operating instructions, one or more memories, input/output interfaces, communication buses or other links, a display, switches, relays, triacs, or other components necessary to perform desired input/output or other functions.

  • the chamber 53 may be filled with a desired amount of liquid by any suitable technique, such as running the water pump 52 for a predetermined time, sensing a water level in the chamber 53 using a conductive probe sensor or capacitive sensor, detecting a pressure rise in chamber 53 , or using any other viable techniques.
  • the controller 51 may detect that the chamber 53 is completely filled when a pressure sensor 57 detects a rise in pressure indicating that the water has reached the top of the chamber 53 .

  • a sensor 32 may also communicate with the controller 51 and provide a low liquid indication to the controller 51 when a float 31 or other device is detected to be at or below a specified level in the tank 2 .
  • a low level indication may be provided to a user, e.g., via the user input/display 13 , suggesting that the tank 2 be refilled.
  • the controller 51 may control the water pump 52 to operate during a calibration period to assess the performance of the pump. This may be done during a first time that the system 1 is powered up and operated by a user (such as the first time that the user introduces water into the tank 2 ), and/or at a time after initial start up (such as after every 100 operation cycles, once every 6 months, etc.).
  • the controller 51 may assess the performance of the pump during the calibration period, and then base its subsequent control of the pump on the assessment.
  • the controller 51 may normally control the pump to deliver a specific, predetermined volume of water to the chamber 53 such that the chamber 53 is not entirely filled. After calibration is performed, control of the volume of water delivered by the pump 52 may be based on an operation time, which may be determined based on the assessment of pump performance during the calibration period.
  • the controller 51 may command to pump 52 to start pumping with the chamber 53 completely empty.
  • the chamber 53 may be known by the controller 51 to be empty at a time when water is first introduced into the system by a user, or the controller 51 may completely drain the chamber, or request that the user do so, by a drain line not shown in FIG. 1 .
  • the controller 51 may detect an amount of water present in the chamber 53 when the pump 52 starts operation during the calibration period.
  • the controller 51 may stop operation of the pump 52 .
  • the controller 51 may cause the pump 52 to operate for a set period of time and detect the amount of liquid delivered by the pump 52 to the chamber 53 .
  • the controller 51 may determine (or effectively determine) the volume flow rate of the pump 52 during the calibration period based on the time elapsed during the calibration period and the volume delivered.
  • the controller 51 may determine an operation index for the pump that represents the pump's ability to provide a volume flow rate. This operation index may be used to determine operation times for the pump when subsequently controlling the pump to deliver other predetermined volumes of liquid. For example, in a subsequent operation, the controller 51 may control the pump to deliver a volume that is 1 ⁇ 2 of the volume delivered during the calibration period. The operation index may be used to determine the operation time for the pump for delivering the smaller volume (which may be 1 ⁇ 2 of the total time elapsed during the calibration period (a calibration time) where other operating conditions for the pump are the same). (A “calibration time” like an operation time, may be any suitable measure for a duration of operation for the pump, not just actual time, e.g., in seconds, but may be an integrated voltage, for example.)

  • the controller 51 may compare the calibration value obtained during calibration to the entries in the lookup table, and identify that entry that is closest to the calibration time.
  • the position of the closest time in the list may be assigned to the pump as its operation index, e.g., if the 10 th entry in the lookup table is the closest to the calibration time, the pump may be assigned an operation index of 10 for subsequent control of the pump.
  • the controller may determine the operation index for the pump based on a power supply characteristic of power supplied to the pump during the calibration period.
  • the use of the power supply characteristic may be used in lieu of other pump performance characteristics, such as volume flow rate.
  • a linear or other curve 3 may be known for the pump that relates a volume flow rate for the pump to voltage supplied to the pump such as that shown in FIG. 3 .
  • the controller 51 may determine the voltage applied to the pump during its operation, and use the voltage to determine an operation index (e.g., relating to a volume flow rate that corresponds to the voltage in the curve 3 ) for subsequent operation of the pump.
  • Such an approach may be useful where voltage supplied to the pump varies due to operation of other portions of the beverage forming system or for other reasons.
  • a beverage forming system may be sold in two different countries which each have different electrical standards with different line voltages.
  • the controller 51 may determine the voltage supplied to the system, and use this voltage to control pump operation.
  • the controller may use two (or more) pump performance characteristics to determine an operation index for the pump.
  • the controller may use both a volume flow rate provided by the pump and a voltage supplied to the pump to determine an operation index.
  • the slope of the curve 3 may be known to be the same for all pumps, but pump-to-pump variations may cause the curve to be shifted (e.g., up or down as shown) for some pumps relative to others. Additionally, the curve may not be linear across all voltages.
  • the controller 51 may determine the voltage provided to the pump as well as the volume flow rate during the calibration period and determine the “shifted” location of the curve 3 for the pump.
  • the shifted curve may be used to determine the pump's operation index for subsequent operation of the pump.
  • the operation index may relate to the shifted position of the curve 3 (e.g., define the “zero crossing” on the voltage axis where a hypothetical zero volume flow rate is provided) and be used to determine an operation time for the pump in subsequent operation based on a desired volume to be delivered and an expected voltage to be supplied to the pump during the operation time.
  • the controller 51 may use a lookup table such as that in FIG. 2 to determine an operation index based on a volume flow rate and voltage provided to the pump.
  • the lookup table in FIG. 2 includes calibration times in “volt-tics” which is a measure of integrated voltage provided to the pump during the calibration period.
  • the controller 51 may measure a current voltage being applied to the pump at regular time intervals (such as every “zero crossing” of a 60 Hz power supply, or every 8.3 milliseconds), and sum the voltage measurements until the desired volume has been delivered to conclude the calibration period.
  • the “volt-tic” measurement may provide a composite indication of time and voltage applied to the pump.
  • the controller 51 may use the “volt-tic” measurement and compare it to the volt-tic values in the lookup table to determine the operation index, e.g., a position of a volt-tic value in the lookup table nearest that of the calibration period may be assigned as an operation index for the pump.
  • the pump may be assigned an operation index from 0 to 49, but larger or smaller index ranges may be used.
  • the number of entries in the lookup table and the range of those entries can be widened or narrowed depending upon the amount of variation in pump rates, across pumps and/or voltages.
  • the controller may determine an operation time for the pump to deliver a predetermined volume of liquid based on an operation index that represents an ability of the pump to provide a volume flow rate for a given voltage supplied to the pump and/or based on voltage supplied to the pump during the operation time.
  • the source of the operation index need not be from a calibration operation performed under the control of the controller, but instead the operation index may be supplied to the controller in any suitable way, such as by programming the controller with the operation index at the time of manufacture of the system.
  • the controller may use the operation index and/or voltage supplied to access a lookup table to identify a suitable operation time for the pump to deliver a desired predetermined volume, or may use the operation index and one or more algorithms to calculate the operation time.
  • a lookup table may include a two dimensional data set in which the controller may identify a suitable operation time (e.g., a volt-tic value) as one that corresponds to the pump's operation index and a voltage to be supplied to the pump during the operation time.
  • a suitable operation time e.g., a volt-tic value
  • the controller may monitor the voltage provided to the pump during operation and adjust or set the operation time as necessary depending on the voltage. For example, the controller may integrate the voltage provided to the pump, and based on the integrated voltage determine a total volume provided by the pump. (Voltage provided to some pumps is directly proportional to the volume flow rate of the pump, and thus an integrated voltage over time may be indicative of a total volume provided by the pump.) One or more correction factors may be used in the calculation, including the operation index.
  • the controller may access a lookup table and based on the operation index, select a “volt-tic” value or other operation time value. For example, the controller may access the lookup table in FIG. 2 and select the volt-tic value that corresponds to the pump's operation index. The volt-tic value in the lookup table may correspond to a different volume than that desired for the pump to provide.
  • the controller may multiply the volt-tic value from the lookup table by a factor to determine a volt-tic value that corresponds to a different volume (e.g., if the pump is to provide a volume of 6 ounces to the chamber 53 , the controller may multiply the volt-tic value obtained from the lookup table by 6/24).
  • the controller may maintain another lookup table that is specific to the volume to be delivered by the pump, such that the controller may access and use the volt-tic value corresponding to the pump's operation index without using a volume correction factor or other operation.
  • This volt-tic value may then be used to operate the pump, e.g., the controller may sample the voltage provided to the pump during the operation time in much the same way as described above for a calibration operation, and decrement the operation time volt-tic value by the voltage measurement made at each interval. When the volt-tic value is decremented to “0”, the pump may be stopped.
