Abstract
According to an embodiment of the present invention, a refrigerator comprises: a cabinet; a grill pan assembly having a channel guiding a flow for supplying cool air to a storage space, and an outlet for discharging the cool air; and a filter device mounted on the grill pan assembly, wherein the filter device comprises a front part, a frame part for accommodating a filter member, and an LED module for emitting light at the filter member, and the filter member comprises a photocatalyst for removing pollutants or bacteria adsorbed on the filter member in response to the visible light emitted from the LED module.
Claims16
A refrigerator comprising:
- a cabinet having a storage space;
- a grille fan assembly that defines an inner surface of the storage space, the grille fan assembly having (i) a channel configured to guide a flow of cold air generated in an evaporator, and (ii) an outlet configured to discharge the cold air to the storage space;
- and
- a filter device mounted on the grille fan assembly,
- wherein the filter device comprises:
- a front portion exposed to a front side of the grille fan assembly,
- a frame part that extends rearward from the front portion and is located inside the channel, the frame part being configured to accommodate a filter member, and
- a light emitting diode (LED) module configured to emit visible light to the filter member,
- wherein the filter member comprises a photocatalyst configured to remove pollutants or bacteria adsorbed on the filter member in response to the visible light emitted from the LED module,
- wherein the grille fan assembly comprises a grille plate that defines a rear surface of the storage space, the grille plate defining the outlet therein, and
- wherein the grille plate further defines a mounting part recessed from a front surface of the grille plate and configured to accommodate the front portion of the filter device.
