Abstract
A refrigerator may be provided with a dispenser which includes a nozzle pipe; a light source that radiates ultraviolet light from one end of the nozzle pipe to an inner space of the nozzle pipe, a window that is provided between the one end of the nozzle pipe and the light source, and a liquid supplying hose barb connected to the nozzle pipe via an elbow. Liquid exiting the elbow swirls as ultraviolet light is irradiated onto the liquid.
Claims18
A refrigerator, comprising:
- a cabinet having a storage space;
- and
- a door configured to open or close the storage space, the door having a dispenser, wherein the dispenser comprises:
- a dispenser housing;
- a nozzle coupling hole formed in a lower portion of the dispenser housing, wherein a key groove is formed in the nozzle coupling hole;
- a nozzle pipe having a key, the nozzle pipe being configured to be inserted in the nozzle coupling hole and the key being configured to be inserted in the key groove to couple the nozzle pipe to the dispenser housing;
- a liquid-supplying hose barb extending, via an elbow, from the nozzle pipe at an inclination with respect to the nozzle pipe;
- and
- a hose coupled to the liquid-supplying hose barb,
- wherein the nozzle pipe comprises:
- a first end which receives liquid;
- a second end through which the liquid is discharged;
- a funnel space provided at the first end of the nozzle pipe that communicates with the liquid-supplying hose barb;
- and
- a cylindrical space that connects with the funnel space and is provided at the second end of the nozzle pipe,
- wherein:
- the key is provided on an outer circumferential surface of a portion of the nozzle pipe that defines the cylindrical space;
- and
- the nozzle coupling hole is engaged with the outer circumferential surface of the portion of the nozzle pipe.
