In paragraph 6, The first electrode is a refrigerator disposed on the upper surface of the guide groove.
In paragraph 6, The above rotation guide is, An electrode groove formed on the upper surface of the above guide groove, and A moving member that is coupled to the first electrode and arranged to move together with the first electrode, and inserted into the electrode groove, and A refrigerator comprising an elastic member provided to elastically bias the above-mentioned movable member upward.
In paragraph 8, The above-mentioned moving member includes a magnetic material, and The above-mentioned rotating bar includes a magnet provided on the inner side of the cap, and A refrigerator in which, as the first door is closed, the moving member moves toward the cap by the magnetic attraction of the magnet and the first electrode and the second electrode come into contact.
In Paragraph 9, The above-described moving member is configured to be movable between a first position elastically biased upward by the elastic member and a second position moved downward by the magnetic attraction of the magnet.
In Paragraph 10, A refrigerator in which, when the moving member is positioned at the first position, the lower end of the first electrode is placed inside the electrode groove so as not to be exposed to the guide groove.
In paragraph 6, The above rotation guide is, An electrode groove formed on the upper surface of the above guide groove, and A connecting member comprising a first portion disposed inside the electrode groove and a second portion protruding outside the electrode groove and disposed in the guide groove, and A refrigerator comprising a shaft provided between the connecting member and the electrode groove so that the first part can move within the electrode groove.
In Paragraph 12, The above connecting member is provided to be rotatable about the shaft, and A refrigerator in which the first part contacts or does not contact the first electrode as the connecting member rotates.

In Paragraph 13, A refrigerator in which, as the first door is opened, the connecting member rotates around the shaft by gravity, and the first part and the first electrode are in non-contact.

Description

Refrigerator The present disclosure relates to a refrigerator comprising a rotating bar. A refrigerator is a home appliance that keeps food fresh, comprising a main body having a storage compartment, a cold air supply unit that supplies cold air to the storage compartment to maintain the internal temperature of the storage compartment lower than the external temperature, and a door for opening and closing the storage compartment. Generally, storage rooms are designed with an open front for the entry and exit of food, and this open front is sealed or opened by a door. The door serves to seal the storage room to prevent cold air from leaking out or warm outside air from entering. Refrigerators may include various types of doors, for example, French door type refrigerators in which a left door and a right door are installed together. A French door type refrigerator may include a rotating bar rotatably coupled to the left door or the right door to seal the gap between the left door and the right door. A heater may be built into the interior of the rotating bar to prevent condensation caused by the temperature difference that occurs when the door is opened or closed. To supply power to this heater, a wire may be extended from the refrigerator body through the door hinge to the interior of the rotating bar. However, power supply methods using wires require a structure to accommodate the wires inside the rotating bar, which complicates the internal structure and may degrade thermal insulation performance due to the space required for the wires. Furthermore, the repetitive opening and closing of the door poses risks of electric shock, as well as durability issues such as wire sheath damage and breakage. One aspect of the present disclosure provides a refrigerator capable of supplying power to a heater of a rotating bar without a wire extending from the main body into the door. One aspect of the present disclosure provides a refrigerator with improved thermal insulation performance and a simplified structure by not including a separate part or structure for wire extraction inside the door. One aspect of the present disclosure provides a refrigerator in which a first electrode of a rotating guide and a second electrode of a rotating bar are arranged to come into contact when the door is closed, and power is supplied to a heater of the rotating bar by the contact between the first electrode and the second electrode. The technical problems to be solved in this document are not limited to those mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art to which this invention belongs from the description below. A refrigerator according to the present disclosure comprises: a main body forming a storage compartment; a first door rotatably coupled to the main body to open and close a first area of the storage compartment; a second door rotatably coupled to the main body to open and close a second area of the storage compartment and arranged parallel to the first door; a rotating bar rotatably coupled to the first door and arranged to cover a gap between the first door and the second door when the first door and the second door are closed, and including a heater; a rotating guide disposed in the main body to guide the rotational movement of the rotating bar when the first door or the second door is opened or closed; a first electrode disposed on the rotating guide and to which power is applied from the main body; and a second electrode disposed on the rotating bar and arranged to contact the first electrode to supply power to the heater.
