Agear cover 306 is provided between thecase body 301 and thefront cover 302, to cover thedriving gear 342 and the pair of driven gears 343. Thegear cover 306 is centrally formed with alever installation hole 306 a, to allow one end of thelever 341 to be coupled to thedriving gear 342. Also, alever guide slot 302 b extends lengthwise vertically in one side of thefront cover 302, to guide vertical movement of thelever 341. - One end of the
lever 341 is coupled to the center of thedriving gear 342. Accordingly, as thelever 341 is rotated about one end thereof, thedriving gear 342 is rotated together with thelever 341. The pair of drivengears 343 are arranged at upper and lower positions of the front surface of theice making case 300 and are engaged with thedriving gear 342. As the drivengears 343 are rotated according to rotation of thedriving gear 342, they rotate the pair ofice making trays driving gear 342 is elastically supported in a circumferential direction thereof by a torsion spring (not shown), such that it is rotated in a direction upon receiving an external force applied to thelever 341, and then, is returned to an original position thereof. - As shown in
FIG. 4 , if the user forces thelever 341 to rotate about one end thereof in a state wherein theice making recesses 311 face upward, thedriving gear 342 is rotated in a direction together with thelever 341, and simultaneously, the pair of drivengears 343 and the pair ofice making trays gears 343 are rotated as shown inFIG. 5 , causing the ice made in the pair ofice making trays single lever 341, all the ice made in the pair ofice making trays ice making unit 30. - After the manual external force applied to the
lever 341 is released, thedriving gear 342 is rotated in an opposite direction by an elastic restoration force of the torsion spring, causing thelever 341, the driven gears 343, and the pair ofice making trays FIG. 4 . - Although a few exemplary embodiments of the present invention have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these exemplary embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the claims and their equivalents.
