The present invention relates to an ice maker for a refrigerator. The present invention provides an ice maker for a refrigerator, which is provided at one side of the refrigerator to make ice. The ice maker comprises an ice maker body provided with an ice-making tray for making ice; an ejector rotatably mounted at one side of the ice maker body so as to eject ice made in the ice-making tray to the outside; a water supply hopper provided at one side of the ice maker body and having at least an open portion so that the water supply hopper is supplied with water from a water supply source through a water supply tube and then transfers the water to the ice-making tray; and a hopper cover coupled to the water supply hopper so as to selectively open and close the open portion of the water supply hopper. According to the present invention, it is possible to avoid a phenomenon in which water supplied from an outer water supply source to the water supply hopper splashes to the outside.

Ice maker for refrigerator

A refrigerator having an ice bank includes a rotation shaft to which a transfer unit for transferring ice pieces in the ice bank is connected, and having a coupling groove on an outer circumferential surface of the end thereof; a joint penetrated by the rotation shaft; a driving shaft connected to the joint, and transmitting a driving force of a motor to the joint; and a coupling ring coupled to the coupling groove of the rotation shaft penetrating the joint. Since the coupling ring is locked by the joint, the rotation shaft is prevented from being arbitrarily separated from the joint. The rotation shaft can be rotated in forward and backward directions. Furthermore, since the rotation shaft has a length shorter than a rotation shaft having screw threads and nuts, the motor can have a compact configuration.

Refrigerator having ice bank

An ice making system for a refrigerator is provided. The ice making system includes an ice maker body, an ejector rotatably coupled to the ice maker body that drops ice pieces made by the ice maker body, an ice bank drawably disposed below the ice maker body that stores the ice pieces dropped by the ejector, an ice sensing lever that senses an amount of the ice pieces stored in the ice bank, a lever holding device that elastically supports and couples the ice sensing lever, and a driving force transmitting device that transmits a rotation force received from the ejector to the lever holding device, thereby rotating the lever holding device. The ice sensing lever may move within a predetermined range when an external force is applied to the ice sensing lever.

The present invention relates to a refrigerator having a dispenser. In the present invention, the dispenser is provided in a concave portion of a door to be exposed toward a front surface of the door. A water tank is installed between a rear surface of the dispenser and a door liner defining a rear surface of the door. The water tank stores the water delivered from an external water supply source while the water in maintained at a relatively low temperature and then discharges the water to the outside through the dispenser. Furthermore, in the present invention, a nozzle, through which the water is discharged from the water tank, is directly connected to a drainpipe of the dispenser, so that users may always take out the water maintained at a constant temperature.

Refrigerator having dispenser

A dispenser of a conventional refrigerator supplies only cold water. Therefore, the dispenser cannot meet a variety of users' needs. Further, the conventional refrigerator has a problem in that various kinds of water supplied from a water source cannot be properly purified. The present invention relates to a refrigerator including a main body with a storage space defined therein and a door for opening and closing the storage space. The refrigerator of the present invention comprises a feed tube for guiding water, which is supplied from an external water source to the main body of the refrigerator, to the door; a valve for distributing the water supplied from the feed tube into a plurality of connection tubes; a cooling tank installed within the door for cooling the water supplied through the valve and then storing the cooled water therein; a heater installed within the door for receiving the water supplied through the valve separately from the cooling tank and then heating the received water; and a dispenser for dispensing the hot and cold water supplied from the heater and cooling tank to the outside of the refrigerator through a front surface of the door. The refrigerator further comprises a filter for filtering the water, and the filter is provided at one of the feed tube and connection tubes for supplying the water toward the heater and detachably installed in the storage space defined in the main body of the refrigerator.

The present invention relates to a heater controller and a heater control method of a refrigerator, and more particularly, to a heater controller and a heater control method of a refrigerator, which control a heater mounted in a refrigerator dispenser. In the present invention, a dispenser of a refrigerator door is provided with a water tank. In order to prevent water in the water tank from being frozen over, the heater is mounted at an outside of the water tank. In addition, by measuring an outer surface temperature of the water tank and then recognizing a water temperature in the water tank based on the outer surface temperature of the water tank, the heater is controlled to be turned on/off based on a range of the water temperature in the water tank. Furthermore, in the present invention, an ambient temperature at a position of the refrigerator is measured, and then, the heater outputs heat energy according to a range of the ambient temperature. Then, the heat energy of the heater is transmitted to the water tank. As a result, the water temperature in the water tank is properly controlled, so that the water tank is prevented from being frozen over.

Heater controller and heater control method of refrigerator

The present invention relates to an ice maker for making ice which is installed within a refrigerator. In the ice maker of the present invention, one end of an ice-making container is supported by a frame while the other end thereof is supported by a case of a drive unit The ice-making container is made of metal, and a ground terminal is electrically connected with the ice-making container by a screw for fastening the ice-making container to the case thereby establishing grounding therebeween. The ice maker is provided with a front face plate for connecting the frame and the drive unit in the longitudinal direction along one side of the ice-making container The front face plate is formed with cold air passing-holes for guiding cold air within a freezing chamber of the refrigerator to the ice-making container The cold air passing-holes are provided with louvers for more smoothly guiding the cold air to the air passing-holes, respectively. The drive unit includes a drive lever for driving an ice-sensing lever therein, and a cam follower of the drive lever and a cam of a rotary member are interlocked with each other. The cam is constructed such that a downstream portion thereof is declined toward an outer periphery of the rotary member and is continuously and smoothly connected with the outer periphery.
