Abstract: Disclosed is an endoscope, including: an insertion part including a lighting imaging unit and an insertion tube; and a manipulation part including a manipulation knob and a manipulation wire configured to bend and operate the insertion tube according to manipulation of the manipulation knob, and the manipulation part may include: a coupling part coupled to the insertion part according to a rotation of a dial provided to be rotatably operable, thereby there is an effect that the operator may easily couple the insertion part and the manipulation part to each other through a simple manipulation of turning the dial.

Abstract: A refrigerator includes a cabinet that includes a refrigerator compartment and a freezer compartment. The refrigerator includes a refrigerator compartment door that is located at a left or a right side of the refrigerator compartment, wherein an ice maker and a dispenser are located at the refrigerator compartment door. The refrigerator includes a main water tank that is located in the refrigerator compartment, and that is configured to cool water. The refrigerator includes a water purifying device that is located at the cabinet, and that is configured to purify water. The refrigerator includes a sub-water tank that is located on the refrigerator compartment door, and that is configured to additionally cool water cooled by the main water tank. The refrigerator includes a water supply path that is defined by connections between the water purifying device, the main water tank, the sub-water tank, the dispenser, and the ice maker.
