Climate regulating features for a refrigerator icebox
An ice making assembly mounted on a door of a refrigerator appliance includes an icebox mounted on the door and defining an ice making chamber and an icebox opening to the ice making chamber, an ice storage bin positioned below the icebox for storing ice, wherein an intake slot is defined between the icebox and the ice storage bin, a damper mounted over the icebox opening and being movable between an open position to permit a flow of air through the icebox opening and a closed position to prevent the flow of air through the icebox opening, a drive motor operably coupled to the damper, and a controller in operative communication with the drive motor for selectively pivoting the damper between the open position and the closed position.
1 . A refrigerator appliance defining a vertical direction, a lateral direction, and a transverse direction, comprising:
a cabinet defining a chilled chamber;
a door being rotatably mounted to the cabinet to provide selective access to the chilled chamber;
an icebox mounted on the door and defining an ice making chamber and an icebox opening to the ice making chamber;
a damper mounted over the icebox opening and being movable between an open position to permit a flow of air through the icebox opening and a closed position to prevent the flow of air through the icebox opening; and
a controller configured to open the damper during a first portion of an ice making process and close the damper during a second portion of the ice making process.
2 . The refrigerator appliance of claim 1 , further comprising:
an ice storage bin positioned below the icebox for storing ice, wherein an intake slot is defined between the icebox and the ice storage bin.
3 . The refrigerator appliance of claim 1 , wherein the icebox opening is defined in a top wall of the icebox.
4 . The refrigerator appliance of claim 1 , further comprising:
a drive motor operably coupled to the damper; and
a controller in operative communication with the drive motor for selectively pivoting the damper between the open position and the closed position.
5 . The refrigerator appliance of claim 1 , further comprising a controller configured to:
determine that a dehumidification cycle is needed; and
open the damper for a predetermined amount of time to purge humid air from the ice making chamber.
6 . The refrigerator appliance of claim 5 , wherein the determination that the dehumidification cycle is needed is based on an elapsed time since commencing an ice making process.
7 . The refrigerator appliance of claim 1 , further comprising:
a heating assembly in thermal communication with the icebox for selectively heating the icebox.
8 . The refrigerator appliance of claim 7 , wherein the heating assembly comprises a resistive heater.
9 . The refrigerator appliance of claim 7 , further comprising a controller configured to:
turn on the heating assembly when the damper is in the closed position and an icebox temperature falls below a predetermined threshold.
10 . The refrigerator appliance of claim 1 , further comprising:
a temperature sensor positioned in thermal communication with the icebox.
11 . The refrigerator appliance of claim 1 , further comprising:
a craft icemaker positioned within the icebox.
12 . The refrigerator appliance of claim 1 , wherein the chilled chamber is a freezer compartment of the refrigerator appliance.
13 . The refrigerator appliance of claim 1 , wherein the refrigerator appliance is a side-by-side refrigerator appliance.
14 . An ice making assembly mounted on a door of a refrigerator appliance, the ice making assembly comprising:
an icebox mounted on the door and defining an ice making chamber and an icebox opening to the ice making chamber;
an ice storage bin positioned below the icebox for storing ice, wherein an intake slot is defined between the icebox and the ice storage bin;
a damper mounted over the icebox opening and being movable between an open position to permit a flow of air through the icebox opening and a closed position to prevent the flow of air through the icebox opening;
a drive motor operably coupled to the damper; and
a controller in operative communication with the drive motor for selectively pivoting the damper between the open position and the closed position, wherein the controller is configured to:
determine that a dehumidification cycle is needed; and
open the damper for a predetermined amount of time to purge humid air from the ice making chamber.
15 . The ice making assembly of claim 14 , wherein the icebox opening is defined in a top wall of the icebox.
16 . The ice making assembly of claim 14 , wherein the controller is configured to open the damper during a first portion of an ice making process and close the damper during a second portion of the ice making process.
17 . The ice making assembly of claim 14 , wherein the determination that the dehumidification cycle is needed is based on an elapsed time since commencing an ice making process.
18 . The ice making assembly of claim 14 , further comprising:
a heating assembly in thermal communication with the icebox for selectively heating the icebox, wherein the controller is configured to turn on the heating assembly when the damper is in the closed position and an icebox temperature falls below a predetermined threshold.
19 . A refrigerator appliance defining a vertical direction, a lateral direction, and a transverse direction, comprising:
a cabinet defining a chilled chamber;
a door being rotatably mounted to the cabinet to provide selective access to the chilled chamber;
an icebox mounted on the door and defining an ice making chamber and an icebox opening to the ice making chamber;
a damper mounted over the icebox opening and being movable between an open position to permit a flow of air through the icebox opening and a closed position to prevent the flow of air through the icebox opening;
a heating assembly in thermal communication with the icebox for selectively heating the icebox; and
