Abstract: A refrigerator includes a freezing chamber door provided with an ice-making assembly. Ice made by the ice-making assembly can be immediately drawn out to the outside by opening an exclusively used home-bar door. In addition, an ice-making case is coupled by a coupling formed integrally with the freezing chamber door and the ice-making case without a coupling tool or operation. Moreover, if a water bucket is installed to the ice-making case, a water supply hole of the lower end of the water bucket is opened by an opening and closing structure, so that water in the water bucket is automatically supplied to an ice tray. In addition, an ice-separating lever having a ? shape is provided to simultaneously rotate a plurality of ice trays. Meanwhile, an ice bank cooperates with the home-bar door to be drawn out forward as the home-bar door is opened.

Abstract: An ice detecting apparatus for a refrigerator having an ice maker includes an ice detecting sensor which determines whether or not an ice storage container which receives and stores ice made by the ice maker is full or nearly full of ice based on pulses transmitted from and received by transmitting and receiving units. The ice detecting sensor includes a transmitting unit to transmit one or more pulses and a receiving unit to detect the pulses transmitted from the transmitting unit. A controller is operably coupled to the transmitting and receiving units to determine whether the storage container is full or nearly full based on pulses detected by the receiving unit among one or more pulses transmitted by the transmitting unit. The controller also determines whether or not external light has been introduced into the ice maker based on the pulses detected by the receiving unit.

Abstract: A monitor either usable in cooperation with or apart from a portable cooler to maintain a temperature of medications. The cooling device defines an interior volume for holding the medications, a power source including at least one of a 12 volt DC and an attachable 110 volt AC supply. A portable monitoring device is integrated with the cooling device and further includes a processor driven circuitry for recording a temperature associated with the interior volume containing the medications. The recorded temperature is compared at determined intervals to a preset programmed temperature range and, upon exceeding the programmed range, the device alerts the user. An alternative monitoring device is envisioned to ship with the medication from the manufacturer and remain with the medication container until the medications are used.

Abstract: A manufacturing method of a transition critical refrigerating cycle device in which a gas cooler and a sub-cooler are integrated to constitute one heat exchanger so as to most efficiently cool a refrigerant in the device. The transition critical refrigerating cycle device is constituted by successively connecting a compressor, the gas cooler, a capillary tube and an evaporator, and having a supercritical pressure on a high-pressure side of the device. The sub-cooler cools an intermediate-pressure refrigerant of the device. A ratio of the number of refrigerant pipes of the sub-cooler to the number of refrigerant pipes of the whole heat exchanger is set to 20% or more and 30% or less. The refrigerant pipes of the sub-cooler have a uniform heat transfer area per unit length of each refrigerant pipe.

Abstract: A thermostatic mixing valve including a cold water bypass passageway controlled by a pressure-operated check valve that opens upon a failure of a hot water supply to the valve for use with safety devices, such as eyewash and drench shower stations. The thermostatic mixing valve allows the continued delivery of cold water upon a failure of a hot water supply. The lack of hot water causes a cold water valve opening to be closed by a thermal motor, which retracts upon the lack of hot water, yet the bypass passageway is adapted to allow cold water to bypass the thermal motor-controlled cold water valve opening and be directed to the outlet of the valve.

The water product dispensing system also includes a water filter, with the fault condition indicating a need to replace the water filter.
