An air sanitation device, especially for a refrigerator, includes a housing having a light outlet, an air channel located in the housing, an air detection device and/or an air purification device located in the air channel, an illumination device located in the housing to generate light adapted to pass through the light outlet, and a partition member separating the illumination device from the air channel. Air is adapted to flow along a first side of the partition member. The illumination device is located between a second side of the partition member and the light outlet.

A refrigerator includes a cabinet having a storage space, an evaporator provided at one side of the storage space, and a grill pan assembly forming an inner surface of the storage space, and including a fluid passage to guide cold air, which is generated from the evaporator, to the storage space, and a discharge port to discharge the cold air to the storage space. The fluid passage may include a first fluid passage to receive the cold air supplied from the evaporator, and a second fluid passage communicating with an outlet of the first fluid passage and split into a plurality of fluid passages. A deodorizing device is provided in the first fluid passage to remove odor, and the cold air passing through the first fluid passage is split at the second fluid passage after passing through the deodorizing device.

A refrigerator includes: a cabinet defining a storage space and a machine room that is partitioned from the storage space, the machine room including a compressor and a condenser, a blowing fan provided in the machine room, a guide member configured to guide air from an outside of the machine room into the machine room and discharge air from the machine room to the outside of the machine room, and a deodorizing module that is provided inside the guide member and that is configured to remove an odor from air passing through the guide member.

A refrigerator includes a rear assembly panel coupled with an assembly cover panel that includes at least one vent. At least one circulation fan is positioned between the rear assembly panel and the assembly cover panel and is proximate the at least one vent. A filter is positioned between the rear assembly panel and the assembly cover panel and is coupled to a photocatalyst to form an activated carbon filter. A light-emitting diode (LED) panel assembly includes a plurality of LEDs positioned on the rear assembly panel and is positioned to project light on the activated carbon filter. An air circulation path extends through the at least one vent and the activated carbon filter and is configured to direct air along the air circulation path, and the activated carbon filter is configured to filter airborne bacteria and particulate matter from the air as the air passes through the activated carbon filter.

A refrigerator includes an inner case including (i) a refrigerating case that defines a refrigerator compartment and (ii) a freezing case that defines a freezer compartment, an outer case disposed outside the inner case, a connection duct disposed between the inner case and the outer case, and a refrigerator compartment cold air supply duct that is detachably coupled to a rear inner surface of the refrigerating case and in fluid communication with the connection duct. The connection duct and the refrigerator compartment cold air supply duct are in communication on a rear surface of the refrigerating case with the refrigerating case interposed therebetween, thereby reducing the area occupied by the refrigerator compartment cold air supply duct disposed in the rear inner surface of the refrigerator compartment.

A deodorization module includes a housing having a bar securing member and a substrate securing member, and formed of a reflective material, wherein each of the bar securing member and the substrate securing member protrudes inward from an inner side surface of the housing and has a groove. A photocatalyst bar is disposed such that air introduced into the housing passes through the photocatalyst bar. A light source module including a light source substrate and an ultraviolet (UV) light source is disposed on a first surface of the light source substrate, wherein the light source module is configured to emit light toward the photocatalyst bar. An external guide protrudes outward around an outer periphery of the housing.

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.

A refrigerator includes a storage compartment and an air sanitation device mounted on a top wall of the storage compartment. The air sanitation device includes: a housing having an upper wall, a lower wall, and a peripheral wall connecting the upper wall to the lower wall; an air channel disposed in the housing and has an air inlet and an air outlet; a fan disposed in the air channel to force air to enter the air channel from the air inlet and leave the air channel from the air outlet; and an air detection device and/or an air purification device disposed in the air channel. The air outlet is disposed on the peripheral wall, and the air channel is configured in such a way that the air is discharged out of the air outlet obliquely downward.

There is described a filter assembly (2) comprising a filter housing (15) and a removable filter cartridge (16) arranged and/or arrangeable within the filter housing (15). The filter assembly (2) comprises an expelling device configured to exert an expelling force onto the filter cartridge (16) when being arranged within the filter housing (15) for at least partially directing the filter cartridge (16) out of the filter housing (15) and a control device controllable into a locking configuration for blocking the filter cartridge (16) within the filter housing (15) and/or for counter-acting against the expelling force and an unlocking configuration for allowing the expelling force to at least partially expel the filter cartridge (16) from the filter housing (15). The control device comprises at least a first interaction element (20) and a second interaction element (21) interacting and/or being configured to interact with one another with the control device being controlled into the locking configuration. The first interaction element (20) and the second interaction element (21) are configured such that the interaction between the first interaction element (20) and the second interaction element (21) is interrupted and/or released with the control device being controlled into the unlocking configuration and the filter cartridge (16) is provided with the first interaction element (20) and the filter housing (15) is provided with the second interaction element (21).

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.
