An electrical connector for connecting a light module of an adjustable shelf includes a connector box having a first electrically conductive material electrically connected to a pair of tabs of a frame member formed along a front end of the adjustable shelf, a slide member attached to a side of the connector box and slidable along the frame member to lock the connector box with the adjustable shelf, and a second electrically conductive material having a spring contact positioned on a top side of the connector box. The spring contact is locked to a conductive area of a shelf holder electrically connected to a lead frame of an appliance by sliding the adjustable shelf with respect to the shelf holder. The connector box electrically connects the lead frame and the light module positioned in proximity to the adjustable shelf after the adjustable shelf is mounted to the shelf holder.

A cable harness supplies a plurality of electric devices which are in a distributed arrangement in a device housing. A first connection point of the cable harness has a plug connector on the side of the cable harness. At least the electric devices which are supplied via the first connection point are connected to the first plug connector on the side of the cable harness by way of a device-side plug connector and an adapter that is plugged together with both plug connectors.

A refrigerator may include a cabinet, a drawer, a driving part, a cable tray, and a rack gear assembly. Connecting members of the cable tray may be maintained in an anti-sagging state by a tray guide part, so that friction noise generated during moving of the cable tray is prevented and interference with the cable tray during moving of the drawer is prevented.

A refrigerator includes a cabinet that defines a storage chamber, and a drawer door configured to be inserted into and withdrawn out of the storage chamber. The drawer door includes a drawer part that defines a storage space and a door part configured to open and close the storage chamber based on the drawer door being inserted into and withdrawn out of the storage chamber. An electric device is provided in the door part, and a wiring extends from the cabinet to the drawer door. A wiring guider extends from the cabinet to the drawer door and provides a passageway for the wiring. The wiring guider includes a first linear section connected to the drawer door, a second linear section connected to the cabinet, and a bent section between the first linear section and the second linear section.

A method to control a refrigerator includes changing a transparent display assembly to be in a first or transparent state allowing an inner space of the refrigerator to be visible through the transparent assembly, a second or opaque state so as to conceal the inner space, and a third or a display state to display information on a display of the transparent assembly. The transparent display assembly includes a front panel, a rear panel, an outer spacer configured to maintain a first distance between the front panel and the rear panel, a display provided on a rear surface of the front panel, a light guide plate spaced apart from the display, and a first spacer configured to support the light guide plate and to maintain a second distance between the display and the light guide plate.

A refrigerator includes a main body defining a first cooling space, a door configured to open and close the first cooling space of the main body, a first heat pump module disposed in the main body and configured to cool the first cooling space, an independent refrigerator that is detachably disposed in the first cooling space and defines a second cooling space separate from the first cooling space, a second heat pump module disposed in the independent refrigerator and configured to cool the second cooling space of the independent refrigerator, a main body power supply part that is disposed in the main body and configured to supply power, and an independent power supply part disposed in the independent refrigerator.

A portable refrigerator is configured to be accommodated in a first cooling space of a main refrigerator and defines a second cooling space independent of the first cooling space. The portable refrigerator includes a case that defines an opening, a drawer configured to be inserted into and drawn out from the case through the opening of the case and configured to, based on being inserted into the case, cover the opening and the second cooling space, a temperature control part configured to control a temperature of the second cooling space, a power supply configured to be selectively connected to external power or indirect power, where the indirect power is supplied through the main refrigerator.

A transport refrigeration system including: a transportation refrigeration unit configured to provide conditioned air to a refrigerated cargo space; an energy storage device configured to store DC electrical energy to power the transportation refrigeration unit; and a DC-to-AC variable invertor electrically connecting the energy storage device to the transportation refrigeration unit, the DC-to-AC variable invertor being configured to convert the DC electrical energy from the energy storage device to AC electrical energy in a variable continuous energy output to power the transportation refrigeration unit.

A vacuum adiabatic body according to the present invention includes a conductive resistance sheet which connects a first plate member and a second plate member to each other; a sealing frame which covers the conductive resistance sheet; a part fixing frame which is supported by the sealing frame; and a part which is mounted on the part fixing frame. According to the present invention, the power necessary for operation can be stably supplied while heat loss is prevented.

Proposed is a refrigerator. According to the refrigerator, a storage space (121) may be defined in a cabinet (100), and a machine room (201) may be arranged under the storage space (121). To implement a cooling system, a compressor (610), a condenser (620), and a heat dissipation fan (611) may be included in the machine room (201). In addition, a control module (700) may be provided in the machine room (201) to face an outlet (225b) of the machine room (201). The control module (700) may be installed at a position close to the entrance of the machine room (201) and may be separated frontward from the machine room (201), and thus accessibility to the control module (700) can be enhanced.
