Definitions

  • This invention relates generally to an appliance cabinet construction which allows for the replacement of insulation contained within the cabinet walls. More particularly, the invention is directed to an appliance cabinet, e.g., a refrigerator or freezer, wherein insulation panels contained in the walls thereof, which have failed and which no longer properly insulate the interior of the appliance from the surrounding atmosphere, may easily be removed and replaced with new insulation panels.
  • an appliance cabinet e.g., a refrigerator or freezer
  • Appliances requiring thermal insulation in the walls panel thereof are generally manufactured by providing an outer structural shell of sheet metal, inserting therein an interior liner of a plastic material, and foaming a polyurethane insulation in-situ therebetween.
  • the foamed-in-place insulation adheres to the metal shell and the plastic liner, and cannot thereafter be removed if it fails as a result of, for example, deterioration of the insulation, wetting of the insulation due to the condensation of moisture, etc.
  • some manufacturers of appliances merely place bats of thermal insulation between the outer structural metal shell and the interior plastic liner which is connected thereto. In either case, if the insulation fails, it cannot be removed and replaced with fresh insulation in order to restore the efficiency of the appliance. When the thermal performance of the insulation degrades, the appliance requires more energy to operate.
  • U.S. Patent No. 4,974,914 discloses a refrigerator having an outer metal shell and an inner plastic liner with foamed-in-place insulation therebetween. The insulation is not easily removable from the disclosed cabinet construction.
  • the insulated appliance comprises: (a) at least one structurally independent inner liner panel;
  • the appliance cabinet construction of the present invention is particularly useful for manufacturing refrigerators and freezers.
  • Figure 1 is a schematic, exploded, perspective view of portions of one embodiment of an insulated appliance, according to the invention.
  • Figure 2 is a schematic, fragmentary, cross- sectional view of an assembled portion of the insulated appliance of Figure 1.
  • FIG 3 is a schematic, exploded, perspective view of a door, according to the invention, which may be used in conjunction with the insulated appliance of Figure 1.
  • insulated appliance as it is used herein is meant a domestic or commercial appliance which conventionally uses thermal or acoustical insulation materials to isolate at least a portion of the interior of the appliance from the atmosphere surrounding the appliance, e.g., an oven, a dishwasher, and especially a ref igerator or freezer.
  • the illustrated appliance 10 is generic to a refrigerator or freezer and comprises a base 12 having inner liner wall panels 14, 16, and 18 attached thereto.
  • the base 12 is conventional in nature and typically contains components such as a compressor and heat exchange equipment, rollers for moving the appliance across a floor, etc.
  • the inner liner wall panels 14, 16, and 18 are attached to the base 12 and to one another by conventional fasteners 20, e.g., screws or clips.
  • An inner liner top panel 22 is similarly attached to the inner liner wall panels 14, 16, and 18.
  • the inner liner panels 14, 16, 18, and 22 are made from a structurally rigid material.
  • the panels are made from a fiberglass reinforced plastic such as polyester-based sheet molding compound (SMC) ; although they may be formed from rigid unreinforced polymeric materials such as high density polyethylene, coated metals, etc.
  • SMC polyester-based sheet molding compound
  • the inner liner wall panels 14, 16, and 18 conveniently include shelf support ribs 24 and hanging shelf bracket slots 26 for positioning shelves (not shown) in the interior of the appliance 10. Although three inner liner wall panels 14, 16, and 18 and an inner liner top panel 22 are illustrated in Figure 1, one ordinarily skilled in the art will appreciate that more or less panels may be used in a conventional insulated appliance.
  • the interior cavity of the appliance 10 is formed at least in part by one or more of the inner liner panels.
  • the interior cavity of the appliance 10 may be defined by structures other than the inner liner panels, e.g., the base 12 illustrated in Figure 1.
  • the insulated appliance 10, according to the present invention comprises at least one inner liner panel.
  • Insulation 28 is positioned adjacent the inner liner wall panels 14, 16, and 18, and may be attached thereto by conventional methods such as by the use of an adhesive, fasteners, etc.
  • the insulation 28 typically is a thermal insulation, although an acoustical insulation may be used for an appliance such as a dishwasher.
  • the insulation 28 may comprise any type of insulation conventionally known in the art such as, for example, a fiberglass bat or board, an evacuated insulation panel, a high R super insulation panel such as that disclosed in U.S. Patent No. 5,094,899, etc.
  • additional insulation 30 is positioned adjacent the inner liner top panel 22 of the appliance 10 of Figure 1.
  • decorative wall cover panels 32 are releasably attached to the inner liner wall panels 14, 16, and 18, encasing the insulation 28 therebetween. Attachment may be achieved by any conventional method such as by screw fasteners, snap fitting, etc.
  • Figure 2 illustrates the use of serrated pins 34 extending from the decorative wall cover panels 32 which frictionally fit into mating holes in the inner liner wall panels 14, 16, and 18.
  • the decorative wall cover panels 32 may be made of any material conventionally used for the exterior of appliances including wood, polymeric materials, or painted metal such as is currently used for most household refrigerators and freezers.
  • the decorative wall cover panels 32 may be removed and reattached as necessary in order to access the insulation 28 for the replacement or repair thereof.
  • a decorative top cover panel 36 is likewise releasably attached to the inner liner top panel 22 of the appliance 10 of Figure 1, thereby encasing the additional insulation 30.
  • the insulation 28 and 30 may be attached to the decorative cover panels 32 and 36, respectively, before the decorative cover panels are releasably attached to the inner liner panels 14, 16, 18, and 22.
  • the insulation 28 and 30 may be retained between the decorative cover panels 32 and 36 and inner liner panels 14, 16, 18, and 22 merely by frictional engagement therebetween.
  • more than one thickness of insulation or more than one kind of insulation panel may be used in the insulated appliance 10.
  • This is as opposed to conventional appliances wherein the inner liner and insulation are substantially supported by the outer metal shell.
  • Figure 3 illustrates an exploded view of an appliance door 38, comprising an inner liner door panel 40, a decorative door cover panel 42, and door insulation 44 therebetween.
  • the decorative door cover panel 42 is releasably attached to the inner liner door panel 40, and the door insulation 44 is retained therebetween, as explained above.
  • Conventional hinge mounts 46 on the inner surface of the inner liner door panel 40 allow the door 38 to be hingedly connected to the insulated appliance 10.
  • the inner liner door panel 40 is structurally independent in that it substantially supports the weight of the door insulation 44 and decorative door cover panel 42, and substantially retains its shape when the decorative door cover panel 42 is removed in order to access the door insulation 44.
