Ice bank and refrigerator including same

Abstract

A refrigerator of the present invention comprises: a storage room in which a storage space is formed; a door for opening and shutting the storage room; an ice storage unit which is provided in the storage room or the door and in which an ice storage space is formed; a crushing member which is rotatably provided at the ice storage unit and crushes the ice stored in the ice storage space; a driving unit which provides rotational power for the crushing member and includes a rotary shaft to be rotated in a first direction; a first power transmission unit which is coupled with the rotary shaft and is rotated in a second direction; and a second power transmission unit which is separably coupled with the first power transmission unit and transmits the power of the first power transmission unit to the crushing member.; The refrigerator of the present invention has remarkable industrial applicability since the width of the ice bank can be reduced by dividing the power transmission unit, which transfers the power of a motor unit to the crushing member, into a plurality of power transmission units.

Description

technical field [0001] Embodiments of the present invention relate to an ice storage cylinder of a refrigerator and a refrigerator including the ice storage cylinder. Background technique [0002] Generally speaking, a refrigerator is a device that continuously repeats the freezing cycle to cool the storage room, that is, the freezer or the refrigerator, so as to keep the food fresh for a certain period of time. The above-mentioned refrigeration cycle includes a compressor, a condenser, an expansion mechanism, and an evaporator. [0003] The refrigerator includes a body forming a storage space and a door selectively covering the body. Storage objects can be stored in the storage space, and the user can open the door to take out the storage objects. [0004] In addition, the refrigerator includes an ice making device for making ice cubes and a dispensing device for taking out the ice cubes made by the ice making device to the outside. Here, the above-mentioned ice making d...

Problems solved by technology

Therefore, the thickness of the above-mentioned ice making device is limited to be more than a predetermined thickness

[0006] On the contrary, if the size of the above-mentioned ice making device is reduced in consideration of the storage space of the above-mentioned storage room, especially the ice storage cylinder for storing ice cubes, there is a problem that the amount of ice cubes that can be stored is limited.

[0007] Moreover, the above-mentioned ice storage cylinder is provided with a driving part and a power transmission mechanism to take out ice cubes, and this causes the problem that the ice storage space of the above-mentioned ice storage cylinder becomes narrow due to the volume of the above-mentioned driving part or power transmission mechanism
