Appl. No.:

7/057551

Inventors:

George E. Wallace - Levittown PA
Robert M. Foy - Trenton NJ

Assignee:

Hill Refrigeration Corporation - Trenton NJ

International Classification:

A47F 304

US Classification:

62248

Abstract:

A refrigerated food display case of the closed front type is provided with an improved means for inhibiting the formation of condensation on the front display window. To this end, the display case includes means dividing chilled air circulated within the case, into primary and secondary air curtains flowing across the display window. A heating means mounted only within the secondary air passage operates throughout each refrigeration cycle, to heat only the chilled air flowing within the secondary passage, thereby forming it into a secondary air curtain interposed between the window and the primary, fully chilled flow of air that has passed through the primary air passage and hence has not been exposed to the heating means. The warm air curtain, impinging upon the surface of the window, inhibits the formation of condensate thereon, such as commonly occurs due to the disparity of ambient temperature and the lower, interior case temperature.

US Classification:

Abstract:

A damper system, for a reach-in refrigerated display case of the air-defrosted type utilizes a single gear-reduction, reversible motor to operate between open and closed positions a multiplicity of dampers, all of which must be operated simultaneously. A radial arm on the motor shaft has a pin-and-slot connection to one damper connected to a series of other dampers pivoted about a common axis for joint opening and closing thereof. Each of the connected dampers includes cam means acting upon tongues of a second series of dampers pivoted about a common axis parallel to the axis of the first damper series. When the dampers of the first series are actuated to open position, the cams individual to the dampers of that series act to cause corresponding dampers of the second series to open simultaneously therewith. In a similar fashion, all the dampers are closed simultaneously by reason of their interconnection and cam action. The disclosed invention has particular adaptability for incorporation in refrigerated display cases in which dampers control the inflow and exhaust of ambient air used in the described type of cases for defrost purposes.

Assignee:

Den-Tal-Ez, Inc. - Audubon PA

International Classification:

B01D 2124
A47L 538

US Classification:

210123

Abstract:

An automatically draining vacuum apparatus for collecting a fluid to be vacuumed. The vacuum apparatus includes a vacuum generating source which generates a suction force and a tank for holding the fluid to be vacuumed. The tank includes a vacuum port, an inlet and a drainage opening for emptying fluid held within the tank. The suction force at the vacuum port draws the fluid to be vacuumed into the tank through the inlet and prevents the fluid within the tank from passing from the tank through the drainage opening. A float is located in the tank for closing off the vacuum port to prevent the fluid within the tank from passing through the vacuum port. The float has a positive buoyancy with respect to the fluid and is positioned within the tank such that when the fluid within the tank is above a predetermined level, the suction force at the vacuum port and the float buoyancy maintain the float in a blocking position to at least partially block the vacuum port, creating a second suction force. The second suction force, which is less than the first suction force in the tank, allows the fluid within the tank to drain to a level below the predetermined level to cause the float to move from the blocking position and restore the first suction force in the tank.

Assignee:

Hill Refrigeration Corporation - Trenton NJ

International Classification:

A47F 304

US Classification:

62256

Abstract:

An opened front refrigerated display case having multiple front refrigeration control air curtains and a supplemental refrigerated air curtain passing over the bin area thereof to aid in maintaining of the bin area of the display area of the case in an efficiently refrigerated condition and to minimize the accumulation of frost therein. The display case includes multiple inlets in the upper area above the opened front area and multiple outlets in the lower area below the opened front area to facilitate multiple curtains of controlled air passing thereover. The innermost lower inlet is adapted to also receive therein refrigerated air from a bin cooling air curtain which passes approximately horizontally over the bin area. Air is admitted into the curtain by a bin outlet positioned immediately adjacent to the main refrigeration flow duct path positioned immediately behind the bin area.

Appl. No.:

Inventors:

George E. Wallace - Levittown PA

Assignee:

Emhart Industries, Inc. - Farmington CT

International Classification:

A47F 304

US Classification:

62 82

Abstract:

A refrigerated display case of the wide island type having side-by-side, upwardly opening product display wells, uses its primary air circulating fans and a defrost fan to draw ambient air into the inlet and outlet of the air conduit of one product well, circulate it through the conduit of that well, transfer it to the air conduit of the second well, circulate it through the second conduit, and discharge it to atmosphere through the inlet and outlet of the second conduit. The case incorporates a solid center partition having an opening near the bottom of the case in which the defrost fan is mounted to transfer the air from one product well to the other. A splitter panel and sill at the upper end of the partition prevent the intake air from becoming mixed with the exhausted air. During a defrost cycle the air can be drawn into the first well and exhausted from the second well for the full duration of the cycle. Or, part way through the cycle a complete reversal of air flow can be effected so as to now draw the air into the second well and exhaust it from the first well for the remainder of the defrost cycle.

International Classification:

US Classification:

62256

Abstract:

A wide island, open top refrigerated display case of the air defrost type has a vertical, hollow partition extending centrally and longitudinally of the case. The partition functions, during defrost cycles only, as an air passage through which the flow of defrost air is induced by operation of a defrost fan mounted in a hollow sill extending along the top of the partition. During refrigeration cycles, the fan is idle and there is no air flow within the partition, so that it forms a hollow dead air space operative to insulate from one another the product wells separated by the partition, a feature of particular importance when one well is refrigerated to a temperature different from the other. Various configurations are disclosed, in some of which the air is forced downwardly within the center flue or passage during defrost, while in others the air is drawn upwardly through the defrost passage. In some configurations, the primary fan or fans are operated in a normal forward direction during defrost, while in others they are reversed or are turned off.
