Abstract: An ice maker and a refrigerator having same. The ice maker comprises: a cooling part having a heat dissipation device and a metal piece; a liquid container configured to store liquid; a liquid supply part configured to supply liquid to the liquid container; a moving mechanism configured to rotate and move the liquid container; and a control part. The metal piece is mounted, so that a rod-shaped component made of metal extends downward from a base end to the tip, and the rod-shaped component is cooled by means of the heat dissipation device. The ice-making process is repeated multiple times under the control of the control part, and the following steps are carried out in the ice-making process: a liquid supply step, an ice making step, an avoidance step, a deicing step, and a recovering step. The ice maker can make ice within a short period of time.

Abstract: The disclosure relates to a shielding device for closing a path through which air circulates in a refrigerator and a refrigerator having shielding device. The shielding device includes a forced draft fan cover having a threaded hole formed with a threaded slot; and a drive shaft formed with a thread being screwed with the threaded slot and extended to pass through the threaded hole, where an air duct that allows the air flows from the inside of the forced draft fan cover to the outside is provided between the drive shaft and the forced draft fan cover.
