When power rates are high, the ice-making machine lets the ice level in the bin drop to lower levels and maintains them at the lower levels until power rates drop again. Alternatively, if through monitoring the usage rate of the ice, the ice-making machine determines that at the lower levels the customer will run out of ice, the ice-making machine will make ice regardless of electricity rates.

  • Bin level sensing device 58 comprises a sensor 60, a mount 62 and a wire 64.
  • Sensor 60 is any suitable sensor that senses a level of ice in ice bin 46.
  • sensor 60 is an ultrasonic sensor.
  • Bin level control board 52 includes circuitry to monitor the current ice level in ice bin 46, a plug (not shown) and a user interface knob 66. Bin level control board 52 plugs into main control board 40. Advance feature control board 54 also plugs into main control board 40 via communication cable 56.

  • Display program 102 responds to manual operation of scroll down and up buttons 78 and 80 to scroll down and up through a list of menu items on a menu presented in display area 76.
  • Display program 102 responds to manual operation of select button 82 to make changes to settings, such as electricity rates and the times of day when applicable or other parameters.
  • Display program 102 responds to manual operation of enter button 86 to change from a main menu list to a sub-menu list.
  • Display program 102 responds to manual operation of escape button 84 to back up through the menu.
  • Display program 102 can also display alerts and data in display area 76. Examples of alerts are "service ice machine soon”, “slow water fill”, “long freeze cycle”, “long harvest cycle”, and "high discharge temperature”.
  • Ice-making machine 20 operates in the following manner:
  • Advance feature board 54 obtains electric rates and times of day when those electric rates are in effect. This is done via user interface 72 with manual input, a download via USB port 74 or automatic download from a network, such as the Ethernet or Internet.
  • ice-making machine 20 runs until ice bin 46 is full. 3) If the power rates are not at their lowest, ice-making machine 20 will only run if the current ice level in ice bin 46 sensed by bin level sensing device 58 drops below a predetermined lower level or set point set by the user and will only run until the lower level set point is achieved. In preferred embodiments, the lower level set point can range up to 32 inches below the bottom of the ice machine. 4) If advance feature board 54 determines that the current ice level in ice bin 26 is dropping by more than a predetermined rate, ice-making machine 20 will run to maintain the ice at a level between the user set point and a full point to avoid running out of ice.
  • the predetermined rate is based on a usage factor, for example, in inches per hour, based on ice bin size and machine ice producing capability. The assumption is that the machine starts with a full bin of ice. It then tracks the rate of use as the ice is dropping from the full point to the predetermined lower level cited above. If this rate is too fast, it will start making ice to bring the machine back to the full level. If not too fast, it will let the ice level drop to the predetermined lower level.
  • Advance feature board 54 is an add-on board to the base control system of conventional ice-making machines. It provides additional features that are not incorporated into the base control board.
  • Display area 76 is sized for a plurality of textual lines of a plurality of characters.
  • the display capacity is two lines and 16 characters per line.
  • Display program 102 can present information in any desired language.
  • Display program 102 also presents warnings in display area 76. For example, a warning "Service Ice Machine Soon" could be displayed. This warning alerts the user that there may soon be a problem that will stop ice production if not corrected. Once a warning has been set no further warnings will be acknowledged until the current warning is cleared. Also, a text description regarding service information may be presented in display area 76 with the warning. This information could specify problem such as, long water fill time, freeze and/or harvest times exceeding maximum settings, discharge temperature is nearing a temperature setting that will trip the ice-making machine. Referring to Figs. 4-20, display program 102 uses a menu structure that comprises a main menu 110 (Fig. 4) and a plurality of sub-menus shown in Figs. 5-19.
  • main menu 110 When main menu 110 is presented in display area 76, a user can use scroll down and up buttons 78 and 80 to scroll through the items of the list. To select an item, the user stops the scrolling on the item of interest. For example, the user stops on PGM bin level. The user then presses enter button 86 to select PGM bin level.
  • Display program 102 responds by presenting a sub-menu (Fig. 18) that lists times 1-4 and levels 1-4 for Monday. Other days of the week may also be included in the list, but are not shown.
  • pressing select button 82 will be highlighted, e.g., by an underline or block. If the parameter is not adjustable, it will not be highlighted. In this case, selecting Time 1 will cause Time 1 to be displayed in a format of four character positions "00:00" with the left most position highlighted. Scroll down and up buttons 78 and 80 then are used to select from digits 0 through 9 for the left most position. When the desired digit is reached, select button 82 is pressed to move to the next character position. The procedure is repeated for this character position and the remaining character positions of Time 1. When the right most position has been completed, press enter button 86 to set the parameter. The screen will return to the previous sub menu. Press scroll down button 78 to Leveli and press enter button 86. Pressing select button 82 will load the current selector switch setting from the bin level device. Change the switch position to change the value. When it's set to the desired level, press enter button 86 to set the parameter.
  • buttons could be used for adjustment of the parameters. Press scroll down button 78 until "Utility Rates" is displayed. Press enter button 86 and the submenu of Fig. 20 will be presented. Scroll through adjustable parameters using up and down buttons 80 and 78. To adjust a parameter, press the select button 82. Use scroll up and down buttons 80 and 78 and select button 82 to change values as needed. Press enter button 86 when complete. Adjustable parameters for the electric utility rate function (Fig. 20), for example, may be: Time 1 , Ratel , Time 2, Rate 2, Time 3, Rate 3, Time 4, Rate 4. If the number of rate increments is less than 4, leave the entries as zero and they will be ignored.
  • buttons 78 and 80 are used to scroll through the alphabet.
