An ice maker capable of efficiently making and removing ice cubes. The ice maker includes first and second pulleys, a drive unit, an ice making conveyor, heat/light generating units, and a reflecting member. The first and second pulleys are spaced apart from each other. The drive unit rotates the first and second pulleys. The ice making conveyor is wrapped around the first and second pulleys, and has a plurality of ice making parts which are concavely formed to contain water therein. The heat/light generating units are located in an interior of the ice making conveyor. The reflecting member covers upper and side portions of the heat/light generating units to downwardly reflect and guide heat and the light generated from the heat/light generating units. The ice maker is provided with the heat/light generating units and the reflecting member, thus allowing ice cubes to be efficiently removed from ice making parts located under the heat/light generating units, and minimizing the amount of energy transmitted to the ice making parts located above the heat/light generating units.

Ice maker

A refrigerator which performs various refrigeration cycles by variously changing refrigerant paths, thus accomplishing refrigerant evaporating temperatures suitable for a refrigerator compartment evaporator and a freezer compartment evaporator, respectively, and which cools a selected one of a refrigerator compartment and a freezer compartment as desired to enhance a cooling efficiency and increasing a cooling speed of the refrigerator.

Refrigerator

An apparatus to automatically close a refrigerator door when the door is opened at a predetermined angle or less. The apparatus includes a hinge mechanism having a first hinge shaft provided at the door, which allows the door to be coupled to a refrigerator cabinet and allows the door to be rotated about the hinge shaft, a tension spring provided at the refrigerator cabinet to apply the door with a tension force for closing the door, and a unit to asborb shock generated when the door is closed by the tension spring, and the a unit to absorb shock includes a housing coupled to the cabinet, and a movable shaft which is received in the housing at its one end and connected to the door at the other end to be linearly moved in the housing, and wherein the tension spring is connected to the cabinet at its one end and connected to the movable shaft at the other end to apply the door with a tension force of closing the door. Thus, when the door is opened at an angle of 90 degrees or less, the door is automatically closed and when the door is opened at an angle greater than 90 degrees, the door remains in its position. Accordingly, use of the refrigerator is convenient, and the maximum rotation angle of the door can be controlled according to a user's desire.
