Description

FIELD OF THE INVENTION

The present subject matter relates generally to refrigerator appliances.

BACKGROUND OF THE INVENTION

Refrigerator appliances generally include a cabinet that defines chilled chambers for receipt of food items for storage. Certain refrigerator appliances include a fresh food chamber for storage of food items above the freezing temperature of water and a freezer chamber for storage of food items below the freezing temperature of water. The fresh food chamber and the freezer chamber can be positioned at various locations relative to each other within the cabinet. Consumers generally prefer chilled chambers that facilitate visibility and accessibility of food items stored therein. However, the arrangement of the fresh food chamber and the freezer chamber within the refrigerator appliances' cabinet can affect food items' visibility and accessibility.
In certain refrigerator appliances, commonly referred to as side-by-side style refrigerator appliance, the fresh food chamber is positioned next to the fresh food chamber within the cabinet. Such a configuration can permit easy access to food items stored on doors of the refrigerator appliances. However, the cabinet can be deep and narrow such that accessing food items at a back of the fresh food chamber and/or freezer chamber is difficult.
In other refrigerator appliances, commonly referred to as bottom mount refrigerator appliances, the freezer chamber is positioned below the fresh food chamber in the cabinet. Such a configuration can provide a wide fresh food chamber and/or a wide freezer chamber. However, a depth of the fresh food chamber and the freezer chamber can deep making accessing food items at a back of the refrigerator appliance difficult.
Accordingly, a refrigerator appliance with features for assisting with accessing food items stored therein would be useful.

Each example is provided by way of explanation of the invention, not limitation of the invention. In fact, it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope or spirit of the invention. For instance, features illustrated or described as part of one embodiment can be used with another embodiment to yield a still further embodiment. Thus, it is intended that the present invention covers such modifications and variations as come within the scope of the appended claims and their equivalents.
FIG. 1 provides a front elevation view of a refrigerator appliance 100 according to an exemplary embodiment of the present subject matter. FIG. 2 provides a front elevation view of refrigerator appliance 100 with doors 120 of refrigerator appliance 100 shown in an open position. Refrigerator appliance 100 defines a vertical direction V, a lateral direction L and a transverse direction T (FIG. 5). The vertical direction V, lateral direction V and transverse direction T are mutually perpendicular and form an orthogonal direction system. As discussed in greater detail below, refrigerator appliance 100 includes features for assisting with accessing food items stored therein.
As may be seen in FIGS. 1 and 2, refrigerator appliance 100 includes a cabinet 110 and a pair of doors 120. Cabinet 110 extends between a top portion 111 and a bottom portion 112, e.g., along the vertical direction V. Cabinet 110 also extends between a first side portion 113 and a second side portion 114, e.g., along the lateral direction L.
Cabinet 110 defines a chilled chamber for receipt of food items for storage. In particular, cabinet 110 defines a fresh food chamber 118 therein. Fresh food chamber 118 extends, e.g., along the vertical direction V, between about top and bottom portions 111 and 112 of cabinet 110. Fresh food chamber 118 also extends, e.g., along the lateral direction L, between about first and second side portions 113 and 114 of cabinet 110. Thus, fresh food chamber 118 extends along about a height of cabinet 110, e.g., along the vertical direction V, and a width of cabinet 110, e.g., along the lateral direction L.
Cabinet 110 of refrigerator appliance 100 can be constructed in any suitable manner. For example, cabinet 110 may include an outer case 132 and an inner liner 134. Outer case 132 and inner liner 134 are components of cabinet 110 and are assembled together to form cabinet 110. Outer case 132 is exposed such that outer case 132 can correspond to an outermost layer of cabinet 110. Outer case 132 may be formed by folding a sheet of a suitable material, such as pre-painted steel, into an inverted U-shape to form top and side walls of outer case 132. Inner liner 134 is positioned within outer case 132 and defines fresh food chamber 118 of cabinet 110. Inner liner 134 can be formed from any suitable material, such as molded plastic. Insulating material 135 (FIG. 5), such as rigid polyurethane foam, is disposed between outer case 132 and inner liner 134 in order to insulate fresh food chamber 118 and provide structural rigidity for cabinet 110.
Doors 120 are rotatably mounted to cabinet 110, e.g., such that doors 120 permit selective access to fresh food chamber 118 of cabinet 110. For example, doors 120 each include a handle 121. A user can pull on handles 121 to adjust doors 120 between a closed position (FIG. 1) and an open position (FIG. 2). In the closed position, doors 120 hinder access to fresh food chamber 118 within cabinet 110. Conversely, doors 120 permit access to fresh food chamber 118 within cabinet 110 when doors 120 are in the open position. As may be seen in FIG. 1, doors 120 extend, e.g., along the vertical direction V, between about top and bottom portions 111 and 112 of cabinet 110. Thus, a top portion 136 of doors 120 is positioned at or adjacent top portion 111 of cabinet 110, and a bottom portion 138 of doors 120 is positioned at or adjacent bottom portion 112 of cabinet 110.
Doors 120 include a first door 122 and a second door 124 rotatably mounted to cabinet 110. First door 122 is rotatably mounted to cabinet 110 at first side portion 113 of cabinet 110. Conversely, second door 124 is rotatably mounted to cabinet 110 at second side portion 114 of cabinet 110.
Turning now to FIG. 2, various storage components are mounted within fresh food chamber 118 to facilitate storage of food items therein as will be understood by those skilled in the art. In particular, the storage components include drawers 162 and shelves 164 that are mounted within fresh food chamber 118. Drawers 162 and shelves 164 are configured for receipt of food items (e.g., beverages and/or solid food items) and may assist with organizing such food items. As an example, drawers 162 can receive fresh food items (e.g., vegetables, fruits, and/or cheeses) and increase the useful life of such fresh food items.
Refrigerator appliance 100 also includes a dispensing assembly 170 for dispensing liquid water and/or ice. Dispensing assembly 170 includes a dispenser 172 positioned on or mounted to an exterior portion of refrigerator appliance 100, e.g., on one of doors 120. Dispenser 172 includes a discharging outlet 174 for accessing ice and liquid water. An actuating mechanism 176, shown as a paddle, is mounted below discharging outlet 174 for operating dispenser 172. In alternative exemplary embodiments, any suitable actuating mechanism may be used to operate dispenser 172. For example, dispenser 172 can include a sensor (such as an ultrasonic sensor) or a button rather than the paddle. A user interface panel 178 is provided for controlling the mode of operation. For example, user interface panel 178 includes a plurality of user inputs (not labeled), such as a water dispensing button and an ice-dispensing button, for selecting a desired mode of operation such as crushed or non-crushed ice.
Discharging outlet 174 and actuating mechanism 176 are an external part of dispenser 172 and are mounted in a dispenser recess 180. Dispenser recess 180 is positioned at a predetermined elevation convenient for a user to access ice or water and enabling the user to access ice without the need to bend-over and without the need to open doors 120. In the exemplary embodiment, dispenser recess 180 is positioned at a level that approximates the chest level of a user.
FIG. 3 provides a perspective view of first door 122 of doors 120. FIG. 4 provides another perspective view of first door 122 of doors 120 with an inner panel 128 of first door 122 shown in an open position to reveal a freezer chamber 130 of an outer casing 126. As may be seen in FIGS. 4 and 4, first door 122 defines a chilled chamber for receipt of food items for storage. In particular, first door 122 defines a freezer chamber 130 therein. As may be seen in FIG. 3, first door 122 includes an outer door portion or casing 126 and an inner door portion or panel 128. Outer casing 126 of first door 122 defines freezer chamber 130. Inner panel 128 is, e.g., rotatably, mounted to outer casing 126 of first door 122 such that inner panel 128 of first door 122 permits selective access to freezer chamber 130 of outer casing 126. Second door 124 can be constructed in a similar manner as first door 122. In particular, second door 124 can define a second freezer chamber therein.
FIG. 5 provides a section view of refrigerator appliance 100. As may be seen in FIG. 5, cabinet 110 extends between a front portion 115 and a back portion 116, e.g., along the transverse direction T. Fresh food chamber 118 extends, e.g., along the transverse direction T, between about front and back portions 115 and 116 of cabinet 110 within cabinet 110. Doors 120 are rotatably mounted to cabinet 110 at front portion 115 of cabinet 110.
As may be seen in FIG. 5, refrigerator appliance 100 also includes a sealed system 140. Sealed system 140 is configured for generating chilled or cooled air, e.g., within fresh food chamber 118 of cabinet 110 and freezer chamber 130 of doors 120. Sealed system 140 includes components for executing a vapor compression cycle for cooling air. The components include a compressor 142, a condenser (not shown), an expansion device (not shown), and an evaporator 144 connected in series and charged with a refrigerant.
Within sealed system 140, gaseous refrigerant flows into compressor 142, which operates to increase the pressure of the refrigerant. This compression of the refrigerant raises its temperature, which is lowered by passing the gaseous refrigerant through the condenser. Within the condenser, heat exchange with ambient air takes place so as to cool the refrigerant and cause the refrigerant to condense to a liquid state. Compressor 142 and the condenser may be positioned with a machinery compartment 141, e.g., at bottom portion 112 of cabinet 110.
The expansion device (e.g., a valve, capillary tube, or other restriction device) receives liquid refrigerant from the condenser. From the expansion device, the liquid refrigerant enters evaporator 144. Upon exiting the expansion device and entering evaporator 144, the liquid refrigerant drops in pressure and vaporizes. Due to the pressure drop and phase change of the refrigerant, evaporator 144 is cool relative to fresh food chamber 118 of cabinet 110 and freezer chamber 130 of doors 120. As such, cooled air is produced and refrigerates fresh food chamber 118 of cabinet 110 and freezer chamber 130 of doors 120. Thus, evaporator 144 is a type of heat exchanger which transfers heat from air passing over evaporator 144 to refrigerant flowing through evaporator 144.
Sealed system 140 is provided by way of example only. Thus, it is within the scope of the present subject matter for other configurations of the sealed system to be used as well. As will be understood by those skilled in the art, sealed system 140 can include additional components, e.g., at least one additional evaporator, compressor, expansion device, and/or condenser. As an example, sealed system 140 may include two evaporators.
Evaporator 144 is mounted to cabinet 110. Evaporator 144 may be positioned adjacent or within fresh food chamber 118 of cabinet 110. A fan 146 is positioned adjacent evaporator 144. Fan 146 is configured for directing chilled air from evaporator 144 to freezer chamber 130 of doors 120. In particular, turning back to FIG. 3, first door 122 defines a freezer chamber entrance 150, e.g., at top portion 136 of first door 122, and a freezer chamber exit 152, e.g., at bottom portion 138 of first door 122. Turning now to FIG. 5, cabinet 110 defines or includes a duct 154, e.g., within insulating material 135. Duct 154 extends between an inlet 156 and an outlet 158. Inlet 156 of duct 154 is positioned at or adjacent evaporator 144 of sealed system 140. Inlet 156 is configured for receipt of chilled air from evaporator 144. Outlet 158 of duct 154 is positioned at or adjacent freezer chamber entrance 150 of first door 122 (FIG. 3). Outlet 158 is configured for directing chilled air out of duct 154 into freezer chamber 130 via freezer chamber entrance 150.
Fan 146 is configured for urging chilled air at or from evaporator 144 into duct 154 at inlet 156 of duct 154 and for urging the chilled air to outlet 158 of duct 154 such that the chilled air enters freezer chamber 130 of doors 120 through freezer chamber entrance 150 of doors 120. In such a manner, freezer chamber 130 of doors 120 can be cooled with chilled air from evaporator 144 in cabinet 110. Refrigerator appliance 100 also includes an ice maker 190 disposed within freezer chamber 130 of doors 120. Ice maker 190 may also be cooled with chilled air from evaporator 144 in cabinet 110.
FIG. 6 provides another section view of refrigerator appliance 100. Refrigerator appliance 100 includes a plurality of bins 160. Bins 160 are mounted to inner panel 128, e.g., on an outer surface 166 of inner panel 128. Bins 160 are positioned or disposed within fresh food chamber 118 of cabinet 110 when doors 120 are in the closed position. Fresh food items or beverages may be positioned or stored within bins 160. Thus, fresh food items or beverages can be stored within fresh food chamber 118 in bins 160 on doors 120.
Refrigerator appliance 100 also a plurality of bins or shelves 192. Shelves 192 are mounted to outer casing 126 of first door 122, e.g., on an inner surface 168 of outer casing 126 such that shelves 192 are disposed within freezer chamber 130 of doors 120. Frozen food items may be positioned or stored on shelves 192. Thus, frozen food items can be stored within freezer chamber 130 on shelves 192 within doors 120.
As discussed above, refrigerator appliance 100 includes both fresh food chamber 118 and at least one freezer chamber 130. In particular, fresh food chamber 118 is defined by cabinet 110, and freezer chamber 130 is defined by one of doors 120. Fresh food items and frozen food items can be stored within refrigerator appliance 100 in fresh food chamber 118 and freezer chamber 130, respectively. In particular, fresh food items can be stored in bins 160 or drawers 162 and on shelves 164 within fresh food chamber 118 and may be accessed by opening and closing doors 120. Similarly, frozen food items can be stored on bins or shelves 192 within freezer chamber 130 and may be accessed by opening and closing inner panel 128 of doors 120.
As may be seen in FIG. 6, freezer chamber 130 of doors 120 is disposed within fresh food chamber 118 of cabinet 110 when doors 120 are in the closed position. Thus, fresh food chamber 118 can be shallow to permit easy access to food items located adjacent back portion 116 of cabinet 110. Similarly, by having freezer chamber 130 on doors 120, a user can easily access food items because freezer chamber 130 is positioned adjacent front portion 115 of cabinet 110.
