Description

BACKGROUND

An ice chute may be used to transfer ice from an ice maker to an ice dispenser. When a freezer door opens, warm air flows into the freezer compartment. After the freezer door closes, the warm air contacts the cold surfaces prior to being evaporated and rapidly cools creating a vacuum in the freezer compartment. To equalize this vacuum, air is pulled through the ice chute into the ice maker assembly causing unwanted frost formation on the ice dispenser.

Ice cap motor 2044 is operated to open dispenser ice cap 504 to allow the ice to be dispensed from an aperture of dispenser assembly 124 mounted in the refrigerated compartment in the illustrative embodiment.
In the illustrative embodiment, ice maker chute plate 500 is mounted to left sidewall 300 of divider wall 114, and first dispenser aperture plate 402 is mounted to right sidewall 202 of divider wall 114. Second dispenser aperture plate 700 is mounted to first dispenser aperture plate 402. Connector ice chute 400 is mounted to second dispenser aperture plate 700 between left sidewall 300 and right sidewall 202 of divider wall 114 within divider wall 114. A right face of ice maker chute plate 500 abuts and seals against a left face of connector ice chute 400.
An ice maker chute aperture wall 502 is formed in ice maker chute plate 500 to define a first aperture through which the ice falls towards dispenser ice cap 504. A dispenser chute aperture wall 702 is formed in second dispenser aperture plate 700 to define a second aperture through which the ice falls towards dispenser ice cap 504. When closed, dispenser ice cap 504 seals against dispenser chute aperture wall 702 and blocks the flow of ice. When open, dispenser ice cap 504 allows the ice to fall through dispenser chute aperture wall 702. In the illustrative embodiment, dispenser ice cap 504 open towards an interior of the refrigerated compartment. After detection of an ice dispense request, ice from ice bin 408 is dispensed through dispenser chute aperture wall 702 through rotation of auger 1702 under control of auger motor 2042. Thus, in the illustrative embodiment, ice is dispensed from ice bin 408 of ice maker assembly 116 positioned in the freezer compartment through divider wall 114 and into and out of a portion of dispenser assembly 124 mounted in the refrigerated compartment.
A vent wall 406 is formed adjacent ice maker chute plate 500 and includes a plurality of apertures through which cooled, dry air can flow up ice chute 404 and down into connector ice chute 400 as described further below. The ice dispensing design may be simplified when the ice is not dispensed from dispenser assembly 124 mounted within the refrigerated compartment. For example, ice maker chute aperture wall 502 and dispenser chute aperture wall 702 may be the same aperture walls configured to dispense ice from within the freezer compartment, and connector ice chute 400 is not needed. As another alternative, dispenser assembly may be mounted to either freezer door 102 or refrigerator door 103 instead of divider wall 114.

Lower air guide plate 1302 and upper air guide plate 1304 extend horizontally from front to back of ice maker assembly 116, in the illustrative embodiment, to direct the cooled, dry air horizontally toward vent wall 406. Lower air guide plate 1302, upper air guide plate 1304, lower deflector wall 1404, and upper deflector wall 1406 reduce a turbulence in the flow of the cooled, dry air toward vent wall 406.
In the illustrative embodiment, vent wall 406 is formed on a back side of ice maker chute plate 500 because the cooled, dry air is flowing from the back to the front where ice chute 404 is located. Vent wall 406 may include a vent aperture wall 1500 and a plurality of ribs 1502. Vent aperture wall 1500 generally extends vertically and horizontally across the air cavity so that the cooled, dry air can flow onto ice chute 404 and into connector ice chute 400. In the illustrative embodiment, the plurality of ribs 1502 extend horizontally across the air cavity to define a horizontal flow of the cooled, dry air. In alternative embodiments, vent wall 406 may include a greater or a fewer number of ribs including zero ribs. In alternative embodiments, the plurality of ribs 1502 may extend vertically across the air cavity. Referring to FIG. 14 , dashed arrows show a general air flow direction through the air cavity.
