Abstract: A vacuum insulated appliance includes a cabinet with an outer wrapper and an inner liner coupled to the outer wrapper to define an insulation cavity. The cabinet defines a passthrough opening through the outer wrapper and the inner liner. A passthrough cover is coupled to the cabinet over the passthrough opening. The passthrough cover has a bottom wall defining at least one service hole. A passthrough cavity is defined between the cabinet and the passthrough cover. At least one foam injection port is defined by the passthrough cover, and an expanding foam is disposed within the passthrough cavity. The expanding foam is configured to be inserted through the at least one foam injection port to at least partially fill the passthrough cavity.

Abstract: A refrigeration appliance includes a vacuum-insulated structure that defines an interior compartment. The vacuum-insulated structure defines a pass-through through the vacuum-insulated structure. The pass-through provides access from an external environment to the interior compartment. An evaporator is disposed within the interior compartment. The evaporator is operable to lower or maintain a temperature of the interior compartment below ambient temperature. A refrigerant line extends through the pass-through and into the interior compartment. A water line extends through the pass-through and into the interior compartment. An insulation block is disposed within the interior compartment and between the evaporator and the water line.

Abstract: A vacuum insulated appliance includes a cabinet with a wrapper and a liner encompassed by the wrapper. A wire on tube condenser is disposed at a rear portion of the cabinet. A plurality of engagement plates is coupled to the wire on tube condenser. Each engagement plate of the plurality of engagement plates includes a slotted feature defined on an end of the engagement plate. The end of each engagement plate extends beyond an outer edge of one of a first side section and a second side section, respectively, of the wire on tube condenser. A plurality of hangers protrudes outward from the rear portion of the cabinet. Each hanger of the plurality of hangers engages with the slotted feature to couple the wire on tube condenser to the cabinet.

Abstract: A cooling appliance includes a body defining a vacuum-insulated chamber. A cooling device is configured to regulate a temperature in the vacuum-insulated chamber. A partition is adjacent to the vacuum-insulated chamber and a compartment is spaced from the vacuum-insulated chamber by the partition. A compressor and a condenser are located in the compartment and at least one coolant tube is in fluid communication with the compressor, the condenser, and the cooling device. A conduit provides power to and extends between the compressor and the condenser. A shroud bracket is located between the compressor and the condenser and defines at least one slot that retains the at least one coolant tube. A drainage routing tube extends from the cooling device to a drain tube mount and the drain tube mount includes a retention feature connected to a drainage receptacle.

Abstract: A refrigeration unit includes a storage compartment, an evaporator compartment, an evaporator disposed within the evaporator compartment, a drain pan beneath the evaporator and having first and second sloped surfaces, and a panel between the storage and evaporator compartments that defines an opening. The storage compartment is in fluid communication with the evaporator compartment via the opening. The refrigeration unit also includes an evaporator fan that delivers air from the evaporator compartment to the storage compartment via the opening, and an evaporator fan grille coupled to the panel and extending outward therefrom into the storage compartment. The evaporator fan grille includes a body that extends over the opening and that is in a spaced-relationship with the panel, and at least one spacer feature extending from the panel to the body.

Abstract: An appliance includes a refrigeration compartment that is defined by a plurality of interior walls. A freezer compartment is positioned proximate to the refrigeration compartment. A compressor is positioned proximate to at least one of the refrigeration compartment and the freezer compartment. A first evaporator is operably coupled to the compressor. A suction line is operably coupled to the first evaporator and is configured to convey refrigerant from the first evaporator toward the compressor. The suction line includes a suction line looping portion that generally defines an inner suction line loop and an outer suction line loop. A capillary tube is operably coupled to the first evaporator and is configured to convey refrigerant to the first evaporator. The capillary tube is configured to contact the suction line looping portion, such that heat from the capillary tube is transferred to the suction line.
