[0031] According to an embodiment of the present invention, the following effects can be achieved.

[0032] First, a cold air return path structure suitable for a storage room can be provided in a vacuum-insulated refrigerator in which a plurality of panels composed of insulation are combined.

[0033] The first duct may be placed in the first storage room (refrigerator). The second duct may be placed in the second storage room (freezer). The second duct accommodates the evaporator. The third duct is connected to the first and second ducts so as to recover the cold air generated by the evaporator.

[0034] A vacuum-insulated refrigerator comprising multiple panels can have joints placed at the corners where the multiple panels are connected. A third duct is placed on one side of the joint. This joint can insulate heat leakage to the corners where the multiple panels are connected.

[0035] Second, one side of the joint is formed in a slanted shape. This optimizes the prevention of heat leakage. The third duct includes a side that can be connected to the slanted side of the joint. This allows the third duct to secure a sufficient amount of recovered cold air without reducing the internal volume.

[0036] Third, a third duct can be placed on either side of the storage chamber, with the evaporator between them. The third duct can evenly distribute the recovered cold air to both sides of the storage chamber. This can disperse frost formed on the evaporator, improving defrosting efficiency. This also allows for smoother circulation of cold air within the refrigerator.

[0037] Fourth, a harness can be incorporated into one side of the third duct facing the joint, forming a structure that wraps around a bundle of multiple wires or signal lines. This allows the harness to be positioned between the joint and the third duct, effectively utilizing the storage space.

[0038] Fifth, a tapered portion can be formed on the side opposite the discharge port of the third duct. This allows for smooth flow of cold air discharged from the third duct toward the evaporator while minimizing resistance.

[0039] Sixth, the defrost heater placed in the evaporator can be extended to the discharge port of the third duct. This can eliminate freezing at the discharge port of the third duct.

[0143] Through this, the third insulation reinforcement part can reinforce the insulation performance of blocking heat leakage through the side of the insulation by wrapping one side of the second panel (103), which is an insulation body, for example, the lower surface of the second panel (103).

[0144] The machine room (111) is configured to accommodate parts of the refrigeration cycle device, such as a compressor, condenser, expander, etc.

The side plate (117a, 117b) and the second plate (116a, 116b, 116c) can be welded or sealed.

[0146] The corners of a refrigerator can experience heat leakage. To insulate this heat leakage, joints can be incorporated at these corners. The corners where multiple panels are connected can be formed by overlapping metal sheets and / or by sealing or welding the overlapping sheets together, which can lead to heat leakage. To insulate this heat leakage, joints are incorporated at the corners where multiple panels are connected.

[0147] The joint includes a joint cover made of plastic material. The joint includes insulation. The insulation can be formed by foaming polyurethane foam into the interior of the joint cover. This prevents heat leakage at the corners where the panels are connected.

The second duct (125) is configured to cover the insulating reinforcement (335). The insulating reinforcement (335) can extend in the Y-axis direction and the Z-axis direction. A cold air path is formed between the insulating reinforcement (335) and the second duct (225).

[0209] The insulating reinforcement (335) may be formed in a plate shape. The insulating reinforcement (335) includes a reinforcing cover (3351) made of a plastic material. The insulating reinforcement (335) includes an insulating material (3352) provided on the inside of the reinforcing cover (3351).

[0210] The reinforcing cover (3351) can be molded using ABS (Acrylonitrile Butadiene Styrene) material. ABS material is easy to process, has high impact resistance, and excellent heat resistance. The insulation material (3352) can be molded by foaming polyurethane foam into the interior of the reinforcing cover (3351).

[0211] Optionally, the insulation reinforcement (335) may be placed on the inside of the defrost tray (128). The defrost tray (128) is placed on one side of the evaporator (113), for example, on the lower side of the evaporator (113).

[0212] Optionally, the insulation reinforcement (335) may be placed on the outside of the defrost water tray (128). One side of the insulation reinforcement (335) and one side of the defrost water tray (128) may be placed adjacent to each other. One side of the insulation reinforcement (335) and one side of the defrost water tray (128) may be connected and / or sealed by a sealing member (3353).

[0213] Since other configurations are the same or similar to the embodiments of FIGS. 1 to 17 described above, duplicate descriptions will be omitted.
