Air circulation structure for a refrigerator machine room

A refrigerator, comprising:

• a cabinet defining a storage compartment therein;
• a machine room defined at a top of the cabinet;
• a main intake vent and a main exhaust vent, located at an upper surface of the machine room so as to allow air to circulate throuah the machine room;
• and
• a noise buffering plate, to divide the machine room into a front chamber and a rear chamber, having at least one vent hole to allow air flow between the front chamber and the rear chamber,
• wherein the front chamber further comprises a partition plate to divide the front chamber into a front intake chamber and a front exhaust chamber.

A refrigerator, comprising:

• a cabinet defining a storage compartment therein;
• a machine room defined at a top of the cabinet, comprising
• a compressor,
• a condenser,
• a cool air circulation fan, and
• a noise buffering plate, to partition the machine room into a front chamber and a rear chamber, the noise buffering plate having a plurality of vent holes to allow air flow between the front chamber and the rear chamber;
• a partition plate, dividing the front chamber into a front intake chamber and a front exhaust chamber;
• a main intake vent, located at an upper surface of the front intake chamber;
• a main exhaust vent, located at an upper surface of the front exhaust chamber;
• and
• a sub-intake vent and a sub-exhaust vent respectively provided at both side edges of the upper surface of the machine room to accomplish an auxiliary circulation of air through the machine room.

A refrigerator, comprising:

• a cabinet defining a storage compartment therein;
• and
• a machine room, comprising;
• a compressor,
• a condenser,
• a cool air circulation fan,
• a main intake vent and a main exhaust vent to allow air to circulate through the machine room, and
• a noise buffering plate,
• the noise buffering plate positioned in the machine room to divide the machine room into a front chamber and a rear chamber and to dampen operational noise from the compressor, condenser, and air circulation fan, having at vent holes to allow air flow between the front chamber and the rear chamber,
• wherein the vent holes are formed through the noise buffering plate such that groups of the vent holes are formed respectively at each side of the noise buffering plate so as to correspond to main intake vent and the main exhaust vent.
