Abstract: An air curtain generator generates an air curtain in a refrigerant compartment of a refrigerator. In the air curtain generator, a sensor senses open and closed states of a refrigerant compartment door. A brushless direct current air curtain fan blows cool air into a refrigerant compartment according to a sensing result of the sensor in order to generate an air curtain in the refrigerant compartment. A direct current power source supplies a direct current driving current to the brushless direct current air curtain fan. A driver drives the brushless direct current air curtain fan. A microcomputer controls an operation of the driver according to the sensing result of the sensor. The air curtain generator maximizes functions of an air curtain generator by applying a brushless direct current air curtain fan having low noise level, low power consumption, and high efficiency thereto.

Abstract: A temperature setting part sets a reference temperature of the interior of a refrigerating compartment of a refrigerator. A door opening/closing detection part detects opening and closing of a door of the refrigerating compartment. First and second temperature detecting parts detect the interior and exterior temperatures of the refrigerating compartment respectively. An air curtain fan driving part drives an air curtain fan. A control part performs a normal cooling operation to control the interior temperature of the refrigerating compartment by driving the cooling fan when the interior temperature is under a reference temperature, drives the air curtain fan with each of the numbers of rotations corresponding to each of several temperature ranges, and performs the normal cooling operation by stopping the driving of the air curtain fan if the closing of the door of the refrigerating compartment is detected.

Abstract: A refrigerated food preparation table having a food preparation surface, a refrigerated food storage chamber, and a food plenum chamber adjacent to the food preparation surface. An air baffle assembly including a venturi restriction creates a resilient and uniform cool air curtain distributed across the top of food bins disposed within the food plenum chamber. One portion of the returning airflow, which is relatively warmer, having been exposed to higher ambient temperatures, circulates around the food bins and another portion of the returning airflow cools the refrigerated food storage chamber before entering a refrigeration coil/blower chamber to begin the cycle anew. The configuration maintains foodstuffs within the unit between 32.degree. and 40.degree. F.

Abstract: A reference temperature of the cooler is set which is required to moderate an interior temperature of the refrigerator. During a defrosting mode, if a door is opened, then a control part switches on an air curtain fan if a temperature of a cooler is lower than the reference temperature, or switches it off if it is not lower. The control part switches off the air curtain fan when the door is closed. Meanwhile, during the defrosting mode, if the door is closed, then the control part switches on the air curtain fan if the temperature of the cooler is lower than the reference temperature in a heating state, or switches it off if it is not lower. The air curtain fan is also switched off if it is not in a heating state. Thus, the air curtain fan is driven depending on interior and exterior conditions during a defrosting operation of the refrigerator. Thereby, refrigerating efficiency as well as defrosting efficiency are increased.

Abstract: A cool air circulation apparatus in a refrigerator provides an upper curved lip extended from a front face of a lower shelf in a refrigerating chamber, by which cool air contacting with ambient air is discharged outside of the refrigerator and only the cool air adjacent to the refrigerating chamber flows into the refrigerating chamber. Accordingly, even though a door of the refrigerating chamber is open for a long time or is opened and closed frequently, ambient air does not enter into the refrigerating chamber and thus cooling efficiency of the refrigerator increases. As a result, a constant temperature in the refrigerating chamber is maintained at all times, thereby being capable of maintaining freshness of a stored foods for a long time.

Abstract: A refrigerator has a blowing fan being capable of blowing bilaterally in a cool air duct. When a door is opened, the blowing fan blows to discharge cool air from the cool air duct, so the air curtain for shutting off a cooling compartment is generated. When the door is closed, the blowing fan blows to draw cool air in the cooling compartment into the cool air duct, so the circulation of the cool air is actively performed, and the cooling efficiency is enhanced.
