1. A refrigerator, comprising:
a freezer space defining a storage space; and
a deep-freezing portion disposed in the freezer space and defining a deep-freeze space that is partitioned from the storage space thereof;
a thermoelectric element module comprising a thermoelectric module having a heat absorbing surface and a heating surface and configured to generate cold air introduced into the deep-freezing portion;
a fan facing the heat absorbing surface of the thermoelectric module and configured to introduce the cold air into the deep-freezing portion; and
an accommodator configured to accommodate the fan and that protrudes from an inner surface of the freezer space,
wherein the deep-freezing portion comprises:
housing having an opening at a front surface thereof and an opening at a rear surface thereof to receive the accommodator, and defining an inner space of the deep-freezing portion,
a door configured to open and close the front surface of the housing, and
