A refrigerator includes a main body having a storage room formed therein, a door that opens and closes the storage room, a filter module, and a cool air circulation fan that circulates cool air through the filter module. The filter module includes a metal photocatalyst filter and a UV LED module for radiating UV rays to the metal photocatalyst filter. The metal photocatalyst filter has photocatalysts made of one of ZnTiO.sub.2, CuTiO.sub.2, AgTiO.sub.2 or FeTiO.sub.2 coated on a filter base. The filter module may allow the entire storage room to be uniformly subject to antibiosis and sterilization at a relatively low cost.

The present invention relates to a system for inhibiting the growth of pathogenic microorganisms, used in refrigerating appliances, air conditioners, and related apparatuses/equipment, using a sterilizing device (1) comprising an upper part (1A) and a lower part (1B), the upper part (1A) being provided with an electronic board (2) with ultraviolet LEDs (3) arranged in a duct (4), and the lower part (1B) having two parallel air circulation ducts (5), which are provided with a plurality of outlets (6), the device (1) being specially designed and located so that ultraviolet light directly impinges on the flow of cool air flowing inside the apparatus, causing the air circulating internally to have a sterilizing effect on the products stored inside a refrigerator or on the air produced by an air conditioner.

A cooling unit has an internal chamber having a linear lighting source (an in-line lighting source) that has a row of light sources. The row of light sources are has at least one visible light section and at least one ultraviolet light section. The visible light sections and the ultraviolet light sections are all aligned in a single line and the visible light section and the ultraviolet light section are alternatingly placed in the line so a visible light section is adjacent to a ultraviolet light section. The visible light section has one or more visible light emitting LEDs and the ultraviolet light section has one or more ultraviolet light emitting LEDs. Each of the visible light emitting LEDs and the ultraviolet light emitting LEDs are all aligned in the line, as well as the visible light sections and the ultraviolet light sections.

Ultraviolet radiation is directed within an area at target wavelengths and/or target intensities. The target wavelength ranges and/or target intensity ranges of the ultraviolet radiation sources can correspond to at least one of a plurality of selectable operating configurations including a storage life preservation operating configuration, a disinfection operating configuration, and an ethylene decomposition operating configuration.

A produce storage chamber designed to fit on a counter top. The produce storage chamber capable of encasing produce, a refrigeration system, at least one ozone generation unit, and at least one ethylene scrubber. The chamber is capable of delaying postharvest produce deterioration using temperature control, ozone generation, and ethylene scrubbing.

An aseptic ice making system includes an ice making system to receive water from a water supply. The ice making system includes an ice producing subsystem to produce ice and a positive air pressure subsystem to maintain a positive air pressure environment within the ice making system.

A perishable storage unit with means for sanitizing food stuffs having a sanitization unit. The storage unit provides a storage body, a door, and a cooling system, wherein the cooling system is integrated with the storage body to maintain a cooling temperature when the door is in a closed position. The sanitization unit includes a light assembly and a switch, wherein the switch is integrated with a peripheral edge of the storage unit such that the door engages the switch when in the closed position. The light assembly is configured to emit sterilizing wavelengths of light, such as ultraviolet light, and is operably coupled to the switch, such that when the door is actuated from an open position to the closed position, the light assembly is switched from an off state to an on state.

Ultraviolet radiation is directed within an area at target wavelengths, target intensities, a target temporal distribution, and/or a target spatial distribution. The target attribute(s) of the ultraviolet radiation can correspond to at least one of a plurality of selectable operating configurations including a storage life preservation operating configuration, a disinfection operating configuration, an ethylene decomposition operating configuration, and/or the like.

A storage apparatus according to an embodiment may include a body having a storage space of storage products and an air purifying module coupled to the body. The air purifying module may include a light emitting diode part disposed along a passage of air to provide ultraviolet light, and a filter part disposed adjacent to the light emitting diode part.

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.
