Provided are an ice maker and a refrigerator including the same. The ice maker for making ice is provided on a rear side of a refrigerator door. A tray cover, a water flood prevention rib, and a rotation guide are provided to prevent flooding of water stored in an ice tray forming the ice maker while the refrigerator door is opened/closed. According to the ice maker and the refrigerator, reduction in a storage capacity of the refrigerator is prevented, flooding of water for making ice is prevented, and the ice maker can be more easily used.

Ice making apparatus and refrigerator comprising the same

A refrigerator is provided. A water supply passage unit of the refrigerator is installed going around a freezing compartment but via an outer side of the main body. Therefore, the water supply passage unit is not frozen.

Refrigerator

Disclosed is a refrigerator includes a main body having a cooling chamber. The refrigerator also includes a dispenser having an accommodation portion positioned at a front side of the refrigerator and configured to provide ice through the accommodation portion without opening a door of the refrigerator. The refrigerator further includes a chute having an outlet, coupled to the dispenser, and configured to transfer ice stored in an ice container to the dispenser. In addition, the refrigerator includes an opening and closing member positioned at the outlet of the chute and configured to open or close the outlet of the chute in response to a driving signal, wherein the opening and closing member and the outlet of the chute have a circular shape.

Refrigerator related technology

Disclosed is a refrigerator having a dispenser, including a main body having a cooling chamber and a door for selectively shielding the cooling chamber. The refrigerator also includes a container accommodating unit and a communication chute that passes through a front surface of the door and guides content to a dispensing cavity defined by the container accommodating unit. The refrigerator further includes an obstruction unit disposed in the container accommodating unit, and movable, about a plane perpendicular to the front which content guided by the communication chute is relatively obstructed by the obstruction unit and a second position in which content guided by the communication chute is relatively unobstructed by the obstruction unit.

Refrigerator having dispenser

A wireless universal serial bus system (WUSB) includes a device, a first host, and a second host. The first host communicates with the device through a first superframe according to a wireless USB protocol. The first host sets a host-adding bit in the first superframe when the second host transfers a second superframe to the first host according to the wireless USB protocol to enable communication between the second host and the device.

A refrigerator includes a main body having cooling chambers for keeping food items therein, a base frame disposed to be movable in outward and inward directions in a lower cooling chamber disposed at a lower portion of the main body, and having a basket door at its front side, a lift frame disposed on the base frame, on which the basket is put, a fluid pressure cylinder mounted at the base frame and connected to the lift frame to lift the lift frame, and an fluid compressor connected to the fluid pressure cylinder by an fluid supply pipe and supplying compressed fluid to the fluid pressure cylinder. Accordingly, as the basket is lifted when being drawn out, a user can take out food items kept in the basket without bending his/her back, which enhances user's convenience.

Refrigerator having basket lift apparatus

A device and method for adaptively controlling a turn-on time of a transceiver so that power consumption is reduced. The device includes a transceiver for receiving a beacon frame broadcasted by a coordinator which coordinates devices, and a controller for determining whether a period of the beacon frame is changed by checking period information in the received beacon frame. The device further includes a beacon frame arrival-time estimation part for estimating an arrival-time of a next beacon frame to be received, based on the changed period information of the beacon frame, a time-error estimation part for estimating a time-errors of the coordinator and the device based on the changed period information of the beacon frame, and a turn-on time estimation part for estimating a turn-on time of a transceiver based on the estimated beacon frame arrival-time and the estimated time-errors.

Device and method for adaptively controlling turn-on time of transceiver

A coordinator's data transmission method, a device's data reception method, a coordinator using the coordinator's data transmission method and a device using the device's data reception method are provided. In a Zigbee system including at least one device and a coordinator for coordinating the device, in a case where a frame pending bit in a beacon frame is determined to be a value representing a direct transmission method, a beacon frame containing an address of a device to receive data and a data transmission time is generated and data is transmitted from the coordinator at the data transmission time. Data transmission time and power consumption can be reduced.

Coordinator's data transmission method, device's data reception method, coordinator using the coordinator's data transmission method, and device using the device's data reception method in Zigbee system

A refrigerator having a basket lift apparatus comprises: a body having cooling chambers for storing food; a basket arranged at the lower cooling chamber to be slidable back and forth and having a door at a front side thereof; a lifting frame arranged at a rear surface of the door to be movable up and down and on which the basket is positioned; and a driving unit for lifting the lifting frame, wherein the lifting frame is composed of a first frame connected to the rear surface of the door to be movable up and down, a second frame extended from an end of the first frame with an inclination angle, and a third frame horizontally extended from an end of the second frame and on which the basket is positioned. In the refrigerator, the basket is attached or detached to or from the lifting frame more easily.

A refrigerator having a basket lift apparatus comprises: a body having cooling chambers for storing food; a basket accommodated in the cooling chamber arranged at a lower portion of the body in a slidable manner back and forth; a basket lift apparatus installed at the basket, for lifting the basket when the basket is drawn out; and a break unit for locking the basket when the basket is lifted to the maximum and thereby preventing the basket from being descended. When the basket is lifted to the maximum, a driving motor is locked thereby to prevent the basket from being descended.

A refrigerator having a basket lift apparatus comprises: a body having cooling chambers for storing food; a basket accommodated in the cooling chamber arranged at a lower portion of the body in a slidable manner; a lifting unit for lifting the basket when the basket is drawn out of the cooling chamber; and a damping unit installed at the lifting unit, for absorbing an impact generated when the basket lifted by the lifting unit is descended. When the basket is descended, a damping force is generated thereby to absorb an impact due to a drastic descent of the basket.

A refrigerator having a basket lift apparatus comprises: a body having cooling chambers for storing food; a basket arranged at the lower cooling chamber arranged at a lower portion of the body to be movable back and forth, and having a door at a front side thereof; a lifting frame arranged at a rear surface of the door to be movable up and down and on which the basket is placed; a driving arm roll-motioned at a lower surface of the lifting frame and hinge-connected to the door, for lifting the lifting frame; a driving unit for rotating the driving arm; and a locking unit installed at the lifting frame, for maintaining a lifted state of the basket by locking the driving arm when the lifting frame is lifted up.

A refrigerator having a basket lift apparatus comprises: a body having cooling chambers for storing food; a basket accommodated in the cooling chamber in a slidable manner; and a basket lift apparatus installed at the basket and lifting the basket when the basket is drawn out of the cooling chamber. When the basket is drawn out of the lower cooling chamber, the basket is lifted by using the basket lifting apparatus thereby to enhance the user's convenience.
