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 method of controlling an ice maker is provided that minimizes generation of excess water and reduces energy consumption. The method allows for uniform heat to be generated and distributed throughout the ice tray during an ice separation process. Consequently, the ice separating process may be consistently performed irrespective of the shape of the ice tray and its surroundings, thereby minimizing generation of excess water, and reducing energy consumption.
Abstract:
An ice maker and a refrigerator having the same include an ice making container which is maintained at a temperature higher than a freezing point of water. Ace core rods having the temperature lower than the freezing point are inserted into the ice making container to cause water in the container to freeze. Accordingly, water at the periphery of the ice making container remains liquid which the water surrounding the ice core rods freezes. As a result, air bubbles generated when the ice is made can be discharged from the liquid portions of the water at the outer edges of the container. This results in ice without trapped air bubbles, which allows excellent transparent ice pieces to be formed. In some embodiments, the exterior surfaces of the ice making container are maintained at a temperature lower than the freezing point of water, and thawing rods maintained at the temperature higher than the freezing point of water are inserted into the center portions of the ice making container. In this embodiment, water at the edges of the ice making container are frozen first, while the water surrounding the thawing rods remains liquid. This also allows air bubbles to escape during formation of the ice, which results in transparent ice pieces.
Abstract:
A method of detecting an amount of ice stored in a storage bin made by an ice maker of a refrigerator, the method comprises applying heat to the ice detecting sensor of the ice maker, detecting an amount stored in the storage bin, and controlling heat application according to the detected amount. The ice maker has an ice detecting sensor attached thereto. A sensor heater provides the heat.
Abstract:
An apparatus for purifying water comprises: a cold water unit configured to store cold water therein; an ice making unit configured to make the cold water into ice cubes; a first heat exchanger configured to supply cold air to the ice making unit; and a second heat exchanger configured to supply cold air to the cold water unit. Since the heat exchangers are individually disposed at the cold water unit and the ice making unit, the temperature of the cold water supplied from the cold water unit may be easily controlled. Furthermore, this may allow the cold water to be supplied to a user with a uniform temperature.
Abstract:
Disclosed is an ice maker for a refrigerator. The ice maker is further provided with an ice making evaporator in addition to an evaporator for cooling a refrigerating chamber of a freezing chamber, and the ice making evaporator is sunk in water to generate ice, thereby quickly creating transparent ice. The ice maker can also be disposed in the refrigerating chamber or a refrigerating chamber door, thus to prevent ice from being formed with air bubble remaining in water, resulting in enhancing transparency of ice. In addition, even if the ice maker is disposed in the refrigerating chamber door, cold air is not needed to be induced from the freezing chamber, which allows independent operations of the freezing chamber and the ice maker, thereby increasing energy efficiency.
Abstract:
An ice tray is provided that prevents the overflow or splashing of water or thin ice out of the ice tray as water is supplied to the ice tray, or when the ice tray is shaken by an external force. The ice tray may include a plurality of receiving portions that receive water for freezing into ice pieces. An overflow preventing portion may extend upward from upper edges of the receiving portions to form a barrier to water flowing out of the ice tray. Alternatively, the receiving parts may be positioned within a corresponding plurality of location parts having water proofing walls extending upward therefrom to inhibit the unintentional flow of water or thin ice out of the receiving portions of the ice tray.
Abstract:
A protective cover for a portable communication device includes a battery cover and a protective cover part coupled with the battery cover. The protective cover is detachably coupled with the portable communication device, and the protective cover part is disposed at a front surface of a display unit part of the portable communication device when the protective cover is coupled with the portable communication device. The portable communication device being turned off/on when the portable communication device is attached to/detached from the protective cover.
Abstract:
A refrigerator and an ice level sensing apparatus are provided. The refrigerator may include a main body, and an ice level sensing apparatus including an optical element for sending or receiving a signal, and an alignment device for aligning and maintaining alignment of the optical element in a preset direction. The sensing apparatus may sense whether an ice storage container in which ice cubes made by an ice maker is at a full ice level. The optical element may be aligned at a preset position, thus preventing movement of the optical element, resulting in improved reliability of the sensing apparatus.
