Abstract
A refrigerator may include a drain hose assembly. The refrigerator includes an upper hose, a lower hose connected to the upper hose while being arranged in a machinery chamber, the lower hose being provided with an air inlet hole to introduce outside air, and an opening and closing unit provided at the lower hose to be upwardly pivoted by negative pressure in a storage chamber and to be downwardly pivoted by gravity, in order to open and close the air inlet hole, respectively. As a result, it may be possible to achieve an enhancement in energy efficiency and to reduce the force required to open door according to an improvement of sealing-tightness.
