Patent number: 6547346Abstract: A refrigerated cabinet (10) includes a cabinet base (20) defining an open top compartment having a refrigerated interior for housing a refrigerated product (50) and a canopy (30) disposed atop the refrigerated compartment. A transparent glass window in the front wall of the canopy (30) is extended downwardly to the product fill line within the refrigerated compartment thereby expanding the customer view area. The rear wall of the canopy (30) includes a transparent service door (40) and a framework (42). The service door (40) may be rotated independently of the framework (42) to an open position providing service access to the refrigerated compartment. The service door (40) and the framework (42) may also be rotated together as a unit to a second open position to provide access to the refrigerated compartment for cleaning and sanitizing. A lamp (80) for illuminating the cabinet interior is disposed externally of the canopy (30).Type: GrantFiled: December 20, 2000Date of Patent: April 15, 2003Assignee: Tyler RefrigerationInventors: Robert T.

Patent number: 6094934Abstract: A refrigeration machine for merchandising and displaying frozen articles. The refrigeration machine has a cabinet having a front wall, opposing side walls and an intermediate support shelf. A top portion of the front wall and the side walls extend above the intermediate support shelf to define a refrigeration unit compartment. The top portion of the front wall has a thicken area and a forward portion of the side walls also have thickened areas that are continuous with the thickened area of the front wall. The thickened areas form a boss which engages a divider wall of a refrigeration unit. The refrigeration unit is removable from the cabinet as a single member. The refrigeration unit has mounts for a compressor and a condenser so that an electrical tray and a condensate tray can be placed under the compressor and condenser. The cabinet has shelf supports that support shelves at varying degrees of inclination.Type: GrantFiled: October 7, 1998Date of Patent: August 1, 2000Assignee: Carrier CorporationInventors: Thomas W.

Patent number: 5974818Abstract: A low temperature frozen food display case that allows a consumer to directly view a frozen product contained therein and which minimizes moisture loss from the frozen food. The display case provides an base member which defines a first portion of a cooling air passageway, side walls extending upwardly from the base member, inner and outer members which are sealed to the side walls and the base member and cooperate to define a second portion of the cooling air passageway. A rear wall defines a plurality of access openings which are selectively closed by pivotal doors. Each of the doors define a third portion of the cooling air passageway through which cooling air from an outlet of the passageway first portion is communicated to the passageway second portion. Food contained within the food storage compartment is not directly contacted by cold air which flows through the cooling air passageway surrounding the storage compartment and, therefore, moisture loss is reduced.Type: GrantFiled: January 28, 1998Date of Patent: November 2, 1999Assignee: White Consolidated Industries, Inc.Inventors: Robert T. Topper, Joseph F. Sanders, William E. Zellner
