Abstract: A control system for a refrigerator having an absorption cooling arrangement and a generator can include a temperature sensor associated with the generator and operable to sense a temperature of the cooling arrangement, a level sensor associated with the refrigerator and operable to sense a level condition of the cooling arrangement, and a heat source operably associated with at least the generator. A control circuit can include a processor and can be in communication with at least the temperature sensor, the level sensor and the heat source, and can be configured to determine a sensed temperature from the temperature sensor and a sensed level condition from the level sensor. The control circuit can be configured to turn off the heat source based on determining the sensed temperature is below a first predetermined threshold or based at least in part on determining the sensed level condition exceeds a second predetermined threshold.

Abstract: A refrigerator shelf support arm includes a main body portion, a hook and a locking mechanism. The main body portion is generally planar in a vertical plane. The hook extends from the main body portion. The hook and the main body portion define an opening therebetween for receiving a portion of the refrigerator to which the arm is to be mounted. The locking mechanism is carried by the main body portion. The locking mechanism is moveable between a first position and a second position such that in the first position the portion of the refrigerator may be received in the opening and in the second position the portion of the refrigerator is captured in the opening.

Abstract: A refrigerator has a cabinet, at least one door and a chilled water dispenser. The at least one door is mounted to the cabinet for movement between a closed position and an open position. The chilled water dispenser includes a nozzle extending from the cabinet. The dispenser is associated with the door and is accessible when the door is in its closed position.

Abstract: A venting arrangement for a vehicle refrigerator including a lower vent assembly and an upper vent assembly. The lower vent assembly provides ventilation intake for cooling of refrigeration components. The upper vent assembly provides ventilation exhaust for cooling of refrigeration components. The venting arrangement further includes a flue exhaust tube assembly. The flue exhaust tube assembly causes the combustion exhaust gases to mix with the ventilation air prior to being exhausted near the upper vent assembly and away from the refrigerator components.

Abstract: The present invention provides control systems and methods for a cooling unit. The system includes a temperature sensor that senses the temperature of a cooling fin and a circuit. The circuit may communicate with a signal from the cooling unit that indicates when cooling is required. The circuit also communicates with the sensor and turns off the heat source of the cooling unit if the temperature does not decrease within a pre-selected time after cooling becomes required. Additionally, the circuit may turn off the heat source only if the temperature is above a pre-selected temperature. Moreover, a pre-selected time after turning off the heat source, the circuit may turn the heat source on.

Abstract: A gas absorption refrigeration apparatus combines two or more separate gas absorption cooling systems. Each cooling system consists of a generator, a condenser, an evaporator, an absorber and tubing connecting the parts to form a complete circulation system for a refrigerant, an absorption liquid and an inert gas. The cooling systems are mounted to a common cabinet with the evaporators of each system being located within the interior insulated compartment of the cabinet. The generator of each cooling system shares a common heat source.

Abstract: A refrigerator for recreational vehicles comprising a generally cubic cabinet having front, back and top sides along with absorbent-type refrigerating apparatus on the back side. A flap member adjustably mounted on the back side at a position above the refrigerating apparatus extends upwardly and outwardly from the cabinet into sealing engagement with the walls of the compartment in the recreational vehicle in which the refrigerator is installed. The configuration of the flap member and the mounting of the flap member so that it can readily be adjusted to a number of positions enhances the ability of the flap member to prevent gases created by the refrigerating apparatus from propagating into the living quarters of the recreational vehicle.

Abstract: Providing an elongated vented drip tray having a narrow solid bottom to be used to collect frost as it melts during the defrosting of a gas absorption type refrigerator. The invention is particularly directed at gas absorption type refrigerators because solid drip trays currently used tend to obstruct airflow within the fresh food compartment. Because gas absorption refrigerators rely on natural convection, placing a solid drip tray inside of the refrigerator compartment beneath the cooling fins of the fresh food compartment somewhat inhibits the free flow of air in that compartment. By providing a vented drip tray, airflow throughout the fresh food compartment is not substantially hindered and airflow may actually increase.
