Abstract:
An improved point-of-sale product chiller that is modular in design and construction whereby the server may be readily produced in various sizes and capacities for point-of-sale display and sale of chilled products. An insulated enclosure includes a base panel, a pair of sidewall panels, and a plurality of modular end wall panels that form a chilled product cavity. The panels are formed of hollow, blow-molded thermoplastic with foam insulation panels inserted therein. A chiller of a desired size is produced by selecting a base panel of the desired size and assembling to it modular end wall panels and sidewall panels of the desired size. One or more insulated central divider panels may be assembled within the enclosure to form multiple chilled product cavities within the enclosure. Removable, flat cold cell panels having cooperating edges are inserted about the inner periphery of the enclosure to maintain product temperatures inside the cavities.
Abstract:
A sectional roll-up door has two generally planar panels having confronting longitudinally extending edges, a hinge between the panels at the edges, a seal extending longitudinally along one of the edges and operatively engageable with the other of the edges, and an element for heating the seal. Each panel comprises a pair of parallel and spaced skins, edge strips bridging the skins and forming the edges, and a mass of insulation between the skins. The heater is provided at the edges.
Abstract:
A bottom structure for refrigerators containing a base plate made of a synthetic resin through an injection molding process and having a cavity filled with foam, a machine compartment casing engages with the top surface of the base plate and defines a machine compartment of a refrigerator, a fitting elements for engaging the lower edge of an exterior casing with the top surface of the base plate is provided, the base plate may have a plurality of fitting slits on its top surface, while the machine compartment casing may have a plurality of fitting projections at positions corresponding to the fitting slits, the fitting elements may include a fitting groove formed on the top surface of the base plate and a fitting rail formed on the lower edge of the external plate.
Abstract:
A refrigerator has a storage compartment defined with two lateral walls and a rear wall. The walls has a liner at its innermost surface and a urethane foam outside the liner. The refrigerator is provided with a passageway defined with a sunken portion of the liner which is depressed toward a urethane foam and a cover plate installed within a storage compartment to cover the sunken portion and having an outlet port through which a cooled-air from an evaporator is introduced into the storage compartment.
Abstract:
An expandable type refrigerator which is capable of coupling a plurality of refrigerating units or freezing units which each have an independent operational cycles and a predetermined size and is easily expanded at the site of refrigerator installation by coupling a plurality of the refrigerating units or freezing units, wherein each refrigerating unit or freezing unit is capable of controlling one micro-controller by using one power cord. The refrigerator includes more than at least two refrigerating units (or two freezing units) each of which is operable with a different operational cycle and which refrigerating units are coupled to each other at an installation site, a coupling apparatus for coupling the refrigerating units, one external power cord for supplying an electric power to the refrigerating units (or the freezing units), and an operational cycle controller for independently controlling the operational cycles of the refrigerating units (or the freezing units).
Abstract:
An insulated door construction such as for use as a refrigerator door having an inner liner secured to an outer panel by a snap-in association. A gasket is secured to the door by a portion of the snap-in retaining structure eliminating the need for screws and gasket retainers. The door is reinforced by corner brackets and cross braces. The brackets may be used to position the liner relative to the outer panel where the insulation in the door is relatively soft insulation, such as fiberglass insulation.
