Refrigerator

A refrigerator comprising:

• a main body comprising:
• an inner liner to form a storage compartment,
• an outer liner to form an external appearance thereof, and
• an insulation member filled between the inner liner and the outer liner;
• a machinery compartment provided at a lower part of the main body, in which a compressor is disposed;
• a pair of flow channel devices respectively provided at opposite sides of the machinery compartment, each flow channel device of the pair of the flow channel devices including:
• an inner wall assembly forming an inner side wall at the inner liner at the one side among the opposite sides of the machinery compartment, the inner wall assembly including:
• a first opening;
• a case unit coupled to the inner wall assembly such that the case unit is disposed between the outer liner and the inner side wall, the case unit including:
• an air flow channel corresponding to the first opening and extended through the insulation member between the inner side wall and the outer liner, the case unit supporting the insulation member filled between the inner liner and the outer liner;
• and
• a cover unit to cover a second opening provided at the outer liner, the second opening corresponding to the air flow channel of the case unit and the first opening, the cover unit having a plurality of ventilation openings.

A refrigerator comprising:

• a main body comprising:
• an inner liner to form a storage compartment,
• an outer liner disposed outside of the inner liner to form an external appearance thereof, and
• an insulation member filled between the inner liner and the outer liner;
• a machinery compartment provided at a lower part of the main body, in which a compressor is disposed;
• and
• a pair of flow channel devices respectively provided at opposite sides of the machinery compartment, each of the flow channel devices including:
• a first opening provided at the inner liner of the machinery compartment at one side among the opposite sides of the machinery compartment, and
• a case unit disposed between the first opening and the outer lining, the case unit extended through the insulation member to interconnect the first opening and a second opening in the outer liner and supporting the insulation member filled between the inner liner and the outer liner.

A refrigerator having a main body including an inner liner defining a storage compartment, an outer liner forming an exterior of the refrigerator, an insulation member formed between the inner liner and the outer liner, and a machinery compartment formed at a lower side of a rear of the main body, the machinery compartment comprising:

• at least one of a compressor and a condenser;
• a heat dissipation fan;
• a machinery compartment cover coupled to a rear of the machinery compartment, the machinery compartment cover including a suction port and a discharge port;
• a pair of flow channel devices respectively provided at opposite lateral sides of the machinery compartment, each flow channel device of the pair of flow channel devices including,
• an inner wall assembly to form an inner side wall at the inner liner at one of the opposite lateral sides of the machinery compartment and an air flow channel extended through the insulation member between the formed inner side wall and the outer liner, the inner wall assembly supporting the insulation member filled between the inner liner and the outer liner.
