The refrigerator may also include a deodorizing case including an upper end part provided on an inner surface of the storage bin, and a lower end part provided on an outer surface of the storage bin. Additionally, a deodorizing member provided in an inner part of the deodorizing case to remove an odor of the storage chamber.

A deodorizing apparatus including: a base, in which a suction port and a discharge port are disposed; a cover coupled to the base; a suction fan fixed to the base so as to suction air through the suction port; a first fixing member disposed between the suction port and the discharge port so as to support a filter; a light emitting module including a light emitting diode; and a second fixing member for supporting the light emitting module. The first fixing member includes a first body part for spacing the filter apart from the base.

A deodorization module including a housing having a suction port and a discharge port formed therein, a fan disposed between the suction port and the discharge port, a photocatalytic filter disposed between the suction port and the fan, a light source module including a substrate and an ultraviolet light source and configured to irradiate the photocatalytic filter with ultraviolet light, and an ion generator disposed between the fan and the discharge port.

Voltage application device includes voltage application circuit. Voltage application circuit applies a voltage to load including discharge electrode that holds liquid, voltage application circuit generating discharge in discharge electrode. During a drive period, voltage application circuit periodically changes a magnitude of the voltage applied to load at a drive frequency within a predetermined range including a resonance frequency of liquid, voltage application circuit mechanically vibrating liquid.

A refrigerator includes a deodorizer installed on an upper surface of a storage compartment. The deodorizer includes a housing in which a flow path is provided, a suction port provided on a lower surface of the housing to suck air, a discharge port provided in the front of the suction port to discharge air, a photocatalytic deodorizing filter disposed at an inner side of the suction port, and a filter light source configured to irradiate light to the photocatalytic deodorizing filter, the flow path is configured to guide air from a rear lower side where the suction port is positioned to a front lower side where the discharge port is positioned, and the filter light source is disposed above the photocatalytic deodorizing filter to face the photocatalytic deodorizing filter in a state of being spaced apart from each other, and positioned above air passing through the flow path.

A refrigerator according to an embodiment of the present invention includes a sterilizing device, wherein the sterilizing device includes a light source assembly which emits visible rays, and a photocatalytic filter which reacts with the visible rays, and the light source assembly is disposed to be inclined at a predetermined angle with respect to a horizontal line equally dividing the photocatalytic filter in a case.

A refrigerator includes a cabinet coupled to one or more doors forming a storage compartment. The refrigerator additionally includes a first fan assembly positioned on an interior surface of a first cabinet wall, and a second fan assembly positioned on the interior surface of a second cabinet wall. The first and second fan assemblies each include: two or more circulation fans; a filter coupled to a photocatalyst to form an activated filter; and a plurality of UV LEDs positioned to project light on the activated filter. An air circulation path is configured to direct air born bacteria and particulate matter within the storage compartment contemporaneously into the first and second fan assemblies using the two or more circulation fans and circulate filtered air into the storage compartment through the activated filter disposed in the air circulation path.

An ethylene absorber unit for a household refrigeration appliance includes a housing and at least one absorber pad which is disposed in a receiving chamber of the housing in such a way that it can be exchanged. A holding duct, which is different from the walls of the housing, is formed in the receiving chamber. The absorber pad is inserted in the holding duct. A household refrigeration appliance having the absorber unit is also provided.

An appliance air freshener having a frame and an air freshener medium. The frame defines an enclosure having a first face, and a second face opposite and spaced from the first face. The first face and the second face form an outer perimeter of the enclosure. The frame also defines a passage located within and spaced from the outer perimeter and extending along a passage axis from the first face to the second face. The air freshener medium is located within the enclosure.

Provided in the present application are an air duct system and a refrigeration appliance provided having the same. The air duct system comprises a drying system and a cooling system arranged in cooperation with each other, the cooling system has an evaporator and an air return port and an air supply port arranged on the two sides of the evaporator, and the drying system is disposed between the air return port and the evaporator, and comprises an air compressor and an air storage tank connected to each other; the air discharged by the air return port passes in sequence through the air compressor and the air storage tank and then flows to the evaporator, so that the air passing through the evaporator is dried, avoiding the problems of frosting and low efficiency.
