A refrigerated cabinet ( ) includes a cabinet base ( ) defining an open top compartment having a refrigerated interior for housing a refrigerated product ( ) and a canopy ( ) disposed atop the refrigerated compartment. A transparent glass window in the front wall of the canopy ( ) is extended downwardly to the product fill line within the refrigerated compartment thereby expanding the customer view area. The rear wall of the canopy ( ) includes a transparent service door ( ) and a framework ( ). The service door ( ) may be rotated independently of the framework ( ) to an open position providing service access to the refrigerated compartment. The service door ( ) and the framework ( ) 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 ( ) for illuminating the cabinet interior is disposed externally of the canopy ( ).

Dipping cabinet with improved lighting

A plurality of frost shields ( ) are removably positioned about the upper circumferential expanse of the walls of the liner ( ) of a refrigerated cabinet ( ). The frost shields ( ) are magnetically mountable to the liner ( ) to facilitate ease of installation and removal. Each frost shield ( ) is a pliable panel fabricated in a layered construction with a relatively thin observe layer ( ) of vinyl mounted on nominally thicker back layer of thermoplastic material ( ) impregnated with magnetic material ( ). Each frost shield ( ) may be provided with a pair of handles ( ) inserted in their respective slots ( ) formed through the frost shield panel.

Frost shield for refrigerated cabinet

An improved ice cream dipping cabinet which readily permits visualization of frozen food product stored therein. The dipping cabinet has an inner box that is at least partially surrounded by an outer box. Cold, refrigerating air is circulated between the inner and outer boxes, cooling the inner box walls and the food product stored therein. The inner and outer boxes have an upper, transparent portion to permit visualization of food products stored within the inner box. The inner box has a door that is hermetically sealed to a top wall thereof to prevent moisture migration from the inner box. The outer box has an open top to permit access to the inner box door.

Modular merchandiser

A refrigerated device having a cooled enclosure and an evaporator through which refrigerant is circulated. An air temperature sensor adapted to generate an air temperature signal indicative of air temperature within the enclosure is provided. A refrigerant temperature sensor adapted to generate a refrigerant temperature signal indicative of refrigerant temperature is provided. A programmable controller adapted to compare the air temperature signal and the refrigerant temperature signal to calculate a difference between the air temperature and the refrigerant temperature is provided. The controller initiates a defrost routine for removing condensate from the evaporator if the difference between the air temperature and the refrigerant temperature is greater or equal to a defrost threshold. Also disclosed are methods for defrosting a refrigerated device and for detecting condensate accumulation.

Microprocessor controlled demand defrost for a cooled enclosure

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. For this, the shelf support have support surfaces and abutment surfaces and the shelves have supported surfaces and stop surfaces.

Freezer

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.

Low temperature static display

A reciprocating piston with an integral valve moves in a first direction within a cylinder to pressurize viscous material contained therein, such as ice cream or the like, thereby pushing it out of a dispensing nozzle located at one end of the cylinder while simultaneously extracting viscous material from a collapsible container into the other end of the cylinder by suctioning the material from the container. When the piston moves in a second direction, the integral valve opens to allow the piston to pass through the previously suctioned viscous material then within the cylinder. The dispensing nozzle includes a normally closed, spring-biased valve opened by the force of the pressurized material, closing of the valve being assisted by a transient suction force occurring as the valved piston begins to move in the second direction through the material. Suctioning the material from the collapsible container, as opposed to compressing the container to expel the material, is preferable when the material contains entrapped gas, as is the case with ice cream, since repeated compression of such containerized material can diminish its quality.
