Abstract:

A refrigeration case monitoring system. In one embodiment, the refrigeration case monitoring system includes a first fiber optic cable, a second fiber optic cable, and a control system having a first sensing channel and a second sensing channel. The first fiber optic cable transmits a signal that is indicative of a refrigeration case condition. The second fiber optic cable transmits a signal that is indicative of a second refrigeration case condition. The control system receives the signals from the first and second fiber optic cables using the first and second sensing channels, processes the signals, and provides an output related to the first and second refrigeration case conditions.

Abstract:

A refrigerated merchandiser that includes a case, a refrigeration system, at least one sensor, a controller, and a display. The refrigeration system is in communication with a product storage area of the case, and discharges a refrigerated airflow into the product storage area to refrigerate product. The refrigeration system includes a compressor, a condenser, and an evaporator coupled in series. The sensor is in communication with the refrigerated airflow to sense an airflow temperature and to generate a signal indicative of the airflow temperature. The controller is in electrical communication with the sensor to receive the signal indicative of the airflow temperature, and includes an algorithm that calculates a temperature of the product based on the signal indicative of the airflow temperature. The display is coupled to the case and is visible from outside the case, and is in electrical communication with the controller to show the calculated product temperature.

Abstract:

An air sanitization system including a housing having an inlet and an outlet, an ozone generator disposed in the housing and positioned between the inlet and outlet, at least one fiber optic cable positioned in visible proximity to the ozone generator, a visible light detector, and a controller. The housing is configured to receive a flow of an oxygen-containing gas through the inlet, and the ozone generator generates ozone from the flow of oxygen-containing gas. The at least one fiber optic cable is configured to receive and transmit visible light from the ozone generator. The visible light detector detects an amount of visible light transmitted by the at least one fiber optic cable. The controller is in communication with the visible light detector for determining whether the amount of visible light transmitted by the at least one fiber optic cable corresponds to a failure of the ozone generator.

Abstract:

A merchandiser communication system including a first plurality of merchandisers arranged in a first row and a second plurality of merchandisers arranged in a second row. Each of the merchandisers includes a light assembly coupled to a case to illuminate a product display area, a light sensor coupled to the case to detect light pulses, and a microcontroller. The light sensor is in visual proximity with one or more of the adjacent merchandisers located across the aisle. The microcontroller is in electrical communication with the light assembly and the light sensor to operate the light assembly to encode the signal in light pulses of the light assembly that are not detectable by a human eye. The communication system also includes a visible light-based communication network in communication with the merchandisers and is operable to communicate the encoded light pulses among the merchandisers via the light assemblies and the light sensors.

US Classification:

62255, 62246, 62440

Abstract:

A refrigerated merchandiser including a case and a refrigeration system in communication with a product storage area of the case. The case includes a case top, a discharge passageway, and a return passageway, and the case top has a lower wall, a front wall, and a deflector. The refrigeration system includes a refrigeration circuit that has a compressor, a condenser, and an evaporator in series, where the evaporator is disposed in the case top. The refrigeration system further includes a fan that cooperates with the lower wall, the front wall, and the deflector to discharge a substantially laminar refrigerated airflow into and through the product storage area to refrigerate the product within a predetermined temperature range without directing the refrigerated airflow directly at the product.

US Classification:

62126

Abstract:

A refrigerated merchandiser including a refrigeration system, a first sensor in communication with the refrigerated airflow in a discharge passageway to sense a discharge airflow temperature, and a second sensor is in communication with the refrigerated airflow in the return passageway to sense a return airflow temperature. A controller is in electrical communication with the first sensor and the second sensor and controls a temperature of the product within a predetermined temperature range that is between about 22 degrees Fahrenheit and 23 degrees Fahrenheit based on at least one of the discharge airflow temperature and the return airflow temperature. The controller is further programmed to operate the refrigeration system such that the discharge airflow temperature is maintained above a temperature between about 10 degrees Fahrenheit and 30 degrees Fahrenheit to regulate an evaporation temperature of the evaporator to avoid freezing the product.

US Classification:

62126

Abstract:

A refrigerated merchandiser including a case, a refrigeration system, a sensor, and a controller. The refrigeration system is operable in a defrost mode defrosting the evaporator, and a refrigeration mode discharging a refrigerated airflow into the product storage area to refrigerate the product and to maintain the product within a predetermined temperature range without freezing the product, and to receive the refrigerated airflow along a return passageway. The sensor senses one or more defrost conditions of the case. The controller controls the refrigeration system in the refrigeration mode and in the defrost mode, and includes an algorithm for calculating when to initiate the defrost mode and for calculating a duration of the defrost mode. The controller is programmed to vary the refrigeration system between the refrigeration mode and the defrost mode based on the signals indicative of the defrost conditions and the calculations by the algorithm.

International Classification:

A47J 3704

US Classification:

99386

Abstract:

An oven-broiler includes modular units each having a tunnel-form cooking chamber formed by a tubular inner member, a heating arrangement extending around at least portions of the inner member for heating same to predetermined temperatures for emission of infrared radiant energy into the chamber for heating of products conveyed therein from one end to the other. The heating arrangement is either electrically energized, thermostatically controlled panels or a gas combustion chamber. The heating arrangement and tubular inner member are enclosed by a tubular outer member supported by a caster-equipped base. Such a modular unit is joinable into a multiple-unit oven of various possible lengths by securement of flanges at opposite ends. Preferably, extensions from opposite ends of the oven orient the entrance and exit for the tunnel-form chamber below floor level of the chamber to entrap a heated oxygen-starved atmosphere therein for substantially flameless heating, cooling, or broiling, and particularly, food products of a greasy nature, such as steaks and chops.
