The present subject matter relates generally to appliances, such as appliances with articulating handles.
Certain appliances include a cabinet and a door. The door is mounted to the cabinet such that the door permits selective access to an interior of the cabinet. For example, bottom mount refrigerator appliances generally include upper refrigerator doors that permit selective access to an upper fresh food chamber and a lower freezer door that permits selective access to a lower freezer chamber. Due a low pressure atmosphere within the freezer chamber, opening the lower freezer door can be difficult and/or challenging.
Certain bottom mount refrigerator appliances include a pivoting handle coupled to a slider to assist with opening the lower freezer door despite the low pressure atmosphere within the freezer chamber. In such refrigerator appliances, the pivoting handle is secured to the door such that the pivoting handle is rotatable about a fixed axis, and the slider is coupled to the pivoting handle such that the slider engages the refrigerator appliances' cabinet and pushes the lower freezer door away from the cabinet when the pivoting handle is rotated. In such a manner, the pivoting handle can assist with opening the lower freezer door. However, such pivoting handles have certain drawbacks. In particular, a substantial gap between the pivoting handle and the lower freezer door is generally required to prevent the pivoting handle from impacting the lower freezer door during rotation of the pivoting handle, and the gap between the pivoting handle and the lower freezer door can be cosmetically unappealing or unattractive.
Accordingly, an appliance with features for assisting with opening a door of the appliance would be useful. In particular, a bottom mount refrigerator appliance with features for assisting with opening a lower freezer door of the bottom mount refrigerator appliance would be useful. In addition, an appliance with features for assisting with opening a door of the appliance and for limiting a gap between a handle of the appliance and the door would be useful.
The present subject matter provides an appliance. The appliance includes a cabinet, a door mounted to the cabinet and a handle. The appliance also includes features for pivotally mounting the handle to the door and for urging the door away from the cabinet when the handle pivots.

For example, outer housing 211 may be mounted or fixed within freezer door 130, e.g., at one of openings 180 of freezer door 130. To assist with properly positioning outer housing 211 within the door of the associate appliance, outer housing 211 includes a front plate 212 and a top plate 213. Front plate 212 and top plate 213 may be place on respective panels of the door of the associated appliance in order to suitably position and/or orient outer housing 211 within the door. For example, front plate 212 may be positioned on a rear surface of outer panel 131 of freezer door 130. Foam insulation may also at least partially surround or encase outer housing 211 within freezer door 130, e.g., in order to assist with securing outer housing 211 within freezer door 130. A gasket 260 may extend between front plate 212 and the rear surface of outer panel 131 of freezer door 130 in order to assist with sealing the openings 180 of freezer door 130, e.g., and hinder or prevent the foam insulation from leaking from freezer door 130 during curing of the foam insulation.
Inner housing 216 may be positioned within and mounted to outer housing 211. In particular, a fastener 262 may extend through inner housing 216 into outer housing 211 in order to removably mount inner housing 216 within outer housing 211. Thus, inner housing 216 may be removably mounted to outer housing 211, e.g., to permit servicing of articulation assembly 200. As may be seen in
Housing assembly 210 also defines a pair of first slots 217 and a pair of second slots 218. As may be seen in
Articulation assembly 200 also includes a handle anchor 220. Handle anchor 220 includes a foot plate 226 and a post 228. A handle of an associated appliance may be mounted to and/or positioned on handle anchor 220. For example, first mounting foot 174 or second mounting foot 176 of handle 170 of freezer door 130 may be positioned on and/or mounted to handle anchor 220. In particular, first mounting foot 174 or second mounting foot 176 of handle 170 of freezer door 130 may be positioned on foot plate 226 of handle anchor 220 and engage post 228 in order to mount the first mounting foot 174 or second mounting foot 176 of handle 170 to handle anchor 220.
At least a portion of handle anchor 220 may be positioned between side walls 219 of inner housing 216 and mounted to inner housing 216. In particular, handle anchor 220 includes a pair of first projections 222 and a pair of second projections 224. First projections 222 and second projections 224 may extend, e.g., along the lateral direction L, towards inner housing 216. Each projection of first projections 222 is, e.g., slidably, received within a respective one of first slots 217 of housing assembly 210. Similarly, each projection of second projections 224 is, e.g., slidably, received within a respective one of second slots 218 of housing assembly 210. Thus, handle anchor 220 may be mounted to housing assembly 210 with first and second projections 222 and 224. In particular, handle anchor 220 may be mounted to housing assembly 210 such that handle anchor 220 is linearly movable and also pivotable within housing assembly 210, as discussed in greater detail below.
Inner housing 216 also includes features for assisting with mounting handle anchor 220 to inner housing 216.
