The subject matter of the present disclosure relates generally to refrigerator appliances and more particularly to air flow paths within and through such appliances for distribution of chilled air.
Refrigerator appliances generally include a cabinet that defines one or more chilled chambers for receipt of food items for storage. One or more insulated, sealing doors are provided for selectively enclosing the chilled food storage chamber(s). Generally, the door(s) are movable between a closed position and an open position for accessing food items stored therein by pulling on the door(s), such as by pulling on a handle on the door.
Typical refrigerator appliances include one or more storage elements in the chilled chamber, such as bins, shelves, baskets, sub-compartments, and other storage elements. In some instances, the storage element or elements may be positioned remote from a chilled air source, such as remote from an inlet from a mechanical compartment of the refrigerator appliance through which chilled air from an evaporator enters the chilled chamber. The refrigerator appliance may include ducts, channels or other enclosed conduits to convey the chilled air to one or more storage elements, such as storage elements that are remote from the point of ingress for chilled air into the chilled chamber. However, such structures may add bulk to the refrigerator appliance, such as may impinge on or reduce the available space within the cabinet for the volume of the chilled chamber. Additionally, such structures may detract from the aesthetics of the refrigerator appliance, e.g., when the structures and outlets thereof are visible within the chilled chamber.
Accordingly, a refrigerator having an improved means for providing an air flow path therein is desired in the art.
Aspects and advantages of the invention will be set forth in part in the following description, or may be apparent from the description, or may be learned through practice of the invention.
In one exemplary embodiment, a refrigerator appliance is provided. The refrigerator appliance defines a vertical direction, a lateral direction, and a transverse direction. The vertical, lateral, and transverse directions are mutually perpendicular. The refrigerator appliance includes a cabinet defining a food storage chamber. The food storage chamber extends between a front side and a back side along the transverse direction. The food storage chamber extends between a floor and a ceiling along the vertical direction. The front side of the food storage chamber defines an opening for receipt of food items. The refrigerator appliance also includes a door positioned at the front side of the food storage chamber. The door is movable between a closed position and an open position to selectively sealingly enclose the food storage chamber in the closed position and provide access to the food storage chamber through the opening in the open position. The refrigerator appliance further includes a storage element positioned at the front side of the food storage chamber such that the storage element is positioned at the front side of the food storage chamber when the door is in the closed position. The ceiling of the food storage chamber includes a front portion, and the front portion of the ceiling of the food storage chamber is angled downward towards the storage element. The ceiling of the food storage chamber thus at least partially defines an air flow path for chilled air to the storage element.
In another exemplary embodiment, a refrigerator appliance is provided. The refrigerator appliance defines a vertical direction, a lateral direction, and a transverse direction. The vertical, lateral, and transverse directions are mutually perpendicular. The refrigerator appliance includes a cabinet defining a food storage chamber. The food storage chamber extends between a front side and a back side along the transverse direction. The food storage chamber extends between a floor and a ceiling along the vertical direction. The front side of the food storage chamber defines an opening for receipt of food items. The refrigerator appliance also includes a door positioned at the front side of the food storage chamber. The door is movable between a closed position and an open position to selectively sealingly enclose the food storage chamber in the closed position and provide access to the food storage chamber through the opening in the open position. The refrigerator appliance also includes a storage element mounted on an interior surface of the door such that the storage element is positioned at the front side of the food storage chamber when the door is in the closed position. The ceiling of the food storage chamber includes a back portion. The back portion of the ceiling of the food storage chamber extends from the back side of the food storage chamber to a peak of the ceiling. The ceiling of the food storage chamber thus at least partially defines an air flow path for chilled air to the storage element.
In still another exemplary embodiment, a refrigerator appliance is provided. The refrigerator appliance defines a vertical direction, a lateral direction, and a transverse direction. The vertical, lateral, and transverse directions are mutually perpendicular. The refrigerator appliance includes a cabinet defining a food storage chamber. The food storage chamber extends between a front side and a back side along the transverse direction. The food storage chamber extends between a floor and a ceiling along the vertical direction. The front side of the food storage chamber defines an opening for receipt of food items. The refrigerator appliance also includes a door positioned at the front side of the food storage chamber. The door is movable between a closed position and an open position to selectively sealingly enclose the food storage chamber in the closed position and provide access to the food storage chamber through the opening in the open position. The refrigerator appliance also includes a storage element mounted on an interior surface of the door such that the storage element is positioned at the front side of the food storage chamber when the door is in the closed position. The refrigerator appliance further includes a light fixture positioned above the ceiling of the food storage chamber. An external surface of the light fixture is mounted flush with the ceiling, such that the external surface of the light fixture at least partially defines an air flow path for chilled air to the storage element.

For example, the back portion 214 may extend upward from the back side 146 of the food storage chamber 122 to the peak 206 of the ceiling 200 at an angle oblique to the transverse direction T. In some embodiments, the back portion 214 of the ceiling 200 may be oriented at an angle of between about 5° and about 30°, such as between about 10° and about 20°, such as about 15°, above the transverse direction T from the back edge 204 to the peak 206. In some embodiments, the front portion 212 of the ceiling 200 may extend downward from the peak 206 of the ceiling 200 to the front edge 202 of the ceiling 200 at an angle oblique to the transverse direction T. In some embodiments, the front portion 212 of the ceiling 200 may be oriented at an angle of between about 1° and about 20°, such as between about 5° and about 15°, such as about 10°, below the transverse direction T from the peak 206 to the front edge 202.
In some embodiments, the refrigerator appliance 100 may include a light fixture 210. For example, the light fixture 210 may be positioned in the front portion 212 of the ceiling 200. The light fixture 210 may be flush with the ceiling 200, e.g., an external surface 211 (
The front portion 212 of the ceiling 200 may be measured from the front edge 202 of the ceiling 200 going backwards (e.g., towards rear side 146 or rear side 110) and/or inwards (e.g., into the food storage chamber 122). In some embodiments, the front portion 212 of the ceiling 200 of the food storage chamber 122 may be up to one half of the ceiling 200 of the food storage chamber 122, such as up to the front half (measured from the front edge 202 as noted) of the ceiling 200. For example, the front portion 212 may be a front one third or a front one quarter of the ceiling 200.
The present disclosure may provide several advantages. For example, the upper boundary of the flow path for chilled air C defined by the ceiling 200 of the food storage chamber 122 may provide improved, e.g., cleaner, aesthetics, e.g., as described above with respect to
