An apparatus, method, or system for filtered air in an interior compartment of a refrigerator. An opening in a wall of the interior liner of the refrigerator defines a channel framing a removable filter cover that tends to be at or near flush with that wall. The filter is positioned behind the cover. The space between the wall opening and the cover functions to provide both air intake into the filter and access lighting around the filter cover.

A refrigerator is provided having at least one internal refrigerated compartment in which a plurality of refrigeration zones are provided, wherein an environment in each refrigeration zone may be independently controlled using a user interface configured to receive a zone selection input from a user indicating one of the plurality of refrigeration zones in which the user desires to adjust the environment; a plurality of lights provided in the internal refrigerated compartment and disposed proximate to each of the plurality of refrigeration zones, wherein groups of the plurality of lights may be separately controlled for visually identifying each of the refrigeration zones; and a controller configured to receive a zone selection input from the user interface, identify a group of the plurality of lights that are disposed proximate the selected refrigeration zone, and control the identified group of the plurality of lights to visually confirm the selected refrigeration zone.

A refrigerator is disclosed. The refrigerator is able to store food at a low temperature and to effectively remove bacteria of the food stored in a storage room, to maintain the storage room clean.

A door for a refrigeration unit having a transparent panel assembly having an outer transparent panel and an inner transparent panel. The outer transparent panel has an outer side, an inner side, and top, bottom, left, and right edges and the inner transparent panel has an outer side, an inner side and top, bottom, left, and right edges. A decorative design is applied to the inner side of the outer transparent panel. A population of light sources are positioned on the top, bottom, left and/or right edges of the outer transparent panel and are capable of emitting light into the outer transparent panel, such that the decorative design is capable of being illuminated by the population of light sources.

A door assembly for an appliance includes a door frame having a top edge and a user interface board positioned at the top edge of the door frame. A console cover is positioned over the user interface board and has a top surface defining a plurality of touch buttons and a front surface defining a front indicator extending at least partially along the vertical direction adjacent the top edge of the door frame. A side-fire light source is mounted on the user interface board for selectively emitting light energy toward the front indicator.

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.

A thermally insulated door assembly includes first and second panes of light transmissive material, a light assembly, and a heat sink. The first pane and the second pane are spaced apart from each other by a separation gap to define an interior chamber. The light assembly is in the interior chamber between the first pane and the second pane, and is configured to generate light within the interior chamber. The heat sink is disposed within the interior chamber and coupled with the light assembly and an inwardly facing surface of the first pane. The heat sink is configured to conduct thermal energy generated by the light assembly onto an inwardly facing surface of the first pane and into the interior chamber such that the inwardly facing surface of the first pane and the interior chamber are heated by the light assembly.

An adjustable door lighting assembly for a refrigerator appliance is provided. In one embodiment, the refrigerator appliance can include a chilled chamber and a door rotatably hinged to the cabinet to provide selective access to the chilled chamber. The adjustable door lighting assembly can include a power track disposed on the door. The adjustable door lighting assembly can include at least one storage bin. The storage bin can include a light emitting device disposed on the storage bin The power track can be configured to deliver power to each respective light emitting device when the storage bin is engaged with the power track.

A refrigerator having a structure in which, when a first door or a second door is opened, a lamp installed at sidewalls of an opening in the first door emits light so that food stored in a door guard disposed in the opening can be illuminated. The refrigerator includes a main body having a storage compartment; a first door that is rotatably disposed in front of the main body and opens/closes the storage compartment, and has an opening formed therein, where at least one door guard is disposed in the opening; a second door that is rotatably disposed in front of the first door, opens/closes the opening, and is rotated in the same direction as the first door; and a lamp installed at the sidewalls of the opening.

A knob assembly includes a knob, a light assembly, a light socket, and a receptacle. The light assembly includes a light diffuser, a light source, and a light connector prong. Light from the light source is transmitted through the light diffuser. The light connector prong is electrically connected to the light source to provide power to the light source when the knob is rotated. The light socket includes a socket housing, a light connector aperture wall, an electrical connector aperture wall, and an internal conductor. The light connector prong is mounted within the light connector aperture wall. A power connector prong connectable to a power source is mounted within the electrical connector aperture wall. The connector housing of the receptacle is configured to house the light socket. The light connector prong is inserted into the light connector aperture wall through a first wall of the device.
