Abstract: A refrigerator includes a refrigerating compartment, a freezing compartment, and an ice-making compartment. The refrigerating compartment is configured to receive cool air from a refrigerating compartment side grille fan assembly, and the ice-making compartment is configured to be located any one refrigerating compartment door and to receive cool air from a freezing compartment side grille fan assembly with the freezing compartment. The refrigerating compartment side grille fan assembly is configured to supply a greater amount of cool air to the side where the ice-making compartment and the refrigerating compartment side grille fan assembly are located, and to perform cool air supply proportional to temperature influence provided from the ice-making compartment and the refrigerating compartment side grille fan assembly.

Abstract: The present invention relates to optical wave guide having multiple independent optical path and optical gas sensor using that, having an effect of improving optical efficiency by elongating optical path and condensing incident light without a separate artificial structure, by using first focus points of multiple 3 dimensional elliptical mirrors as a common focus point and equipping a light source at a first focus point and optical sensor parts at each second focus points in an optical structure using multiple 3 dimensional elliptical mirrors, and by placing so that virtual lines of first elliptical mirror and second elliptical mirror form a constant angle for improving optical efficiency in a structure equipping a light source at a second focus point of any one of elliptical mirror of multiple 3 dimensional elliptical mirrors and optical sensor parts at each second focus points of another 3 dimensional elliptical mirror.

Abstract: The present invention relates to a handle mounting device for use in a refrigerator for mounting a refrigerator door handle onto an outer surface of a door of the refrigerator. The handle mounting device of the present invention is used to mount a handle 50 for opening and closing the door onto an outer surface 40 of the door. The handle mounting device includes a mounting ring member 70 into which one end of handle 50 is fitted and of which a surface is plated, and a handle base 60 which is made of synthetic resin material and of which one end is fitted into the mounting ring member 70 and the other end is fixed onto the outer surface 40 of the door. Further, one end of the handle base 60 is fitted into the handle 50 fitted into the mounting ring member 70.

Abstract: The present invention relates to a handle assembly for a refrigerator. According to the present invention, there is provided a handle assembly for a refrigerator. The handle assembly comprises a pair of handle holders each of which is formed with a cavity therein and mounted onto a front surface of a door by means of a screw that is fastened to the front surface of the door through the cavity; a handle body which is positioned between the handle holders and which is fastened to the handle holders by means of screws that penetrate the handle holders and are fastened thereto; and a handle cover elastically mounted to front ends of the handle holders and the handle body. According to the present invention, since the handle assembly can be mounted to the front surface of the door at the front of the door, the man-hour needed for the assembling works and the production costs can be reduced.
