Abstract
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 portable refrigerator that 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 comprising:
- 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, the drawer being 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;
- and
- a power supply configured to be selectively connected to external power or indirect power, the indirect power being supplied through the main refrigerator,
- wherein the drawer comprises a rolling member configured to facilitate the drawer being inserted into and drawn out from the case and configured to be supported on a floor based on the drawer being drawn out from the case, and
- wherein the rolling member of the drawer is configured to be drawn into the drawer based on the drawer being drawn into the case and to protrude outward of the drawer based on the drawer being drawn out from the case.
A refrigerator that defines a first cooling space, the refrigerator comprising:
- a portable refrigerator that is configured to be accommodated in the first cooling space and defines a second cooling space independent of the first cooling space, the portable refrigerator comprising a power terminal;
- a heat pump configured to cool the first cooling space;
- and
- a power supply configured to supply power to the portable refrigerator accommodated in the refrigerator,
- wherein the power supply comprises:
- a housing,
- a cable disposed in the housing and configured to be connected to the power terminal of the portable refrigerator, and
- an elastic member configured to apply force to the cable based on the cable being drawn out of the housing to be connected to the portable refrigerator, the elastic member being further configured to insert the cable into the housing based on the cable being disconnected from the portable refrigerator.
A refrigerator in which a portable refrigerator that independently forms a second cooling space is accommodated, comprising:
- a heat pump;
- and
- a power supplying part configured to supply power to the portable refrigerator accommodated in the refrigerator,
- wherein the power supplying part comprises:
- a power line and a power line head to be connected to a power terminal of the portable refrigerator;
- and
- an elastic member configured to connect the power line and the power line head to the power terminal of the portable refrigerator in a state in which the power line and the power line head are elastically drawn out, and allow the power line and the power line head to be drawn in when not connected to the portable refrigerator.
