REFRIGERATOR AND OPERATING METHOD THEREOF

摘要

A refrigerator, where warm air is prevented from flowing into a storage chamber during defrosting or when cooling starts, heat transfer from a cooling chamber to the storage chamber is prevented, and the temperature rise in the storage chamber is constrained to a low level. A separator is used to divide a part of an air supply passage, to form a space portion in communication with a cooling chamber through an air supply opening portion. A first freely controllable opening portion is disposed in a separating area between the space portion and the divided air supply passage, and a second freely controllable opening portion is disposed in a separating area between the space portion and an air return passage or the cooling chamber. By setting the first and second opening portions in closed and open states, respectively, a condenser performs cooling and an air blower supplies air.

主权项

1. A refrigerator, comprising:
a storage compartment; a supply air passage, adapted for enabling air to flow into the storage compartment; a return air passage, adapted for enabling the air from the storage compartment to flow through; a cooling compartment, having an air supply opening portion adapted for enabling the air to flow out from the supply air passage and a return air opening portion for enabling the air from the return air passage to flow in; a condenser, disposed inside the cooling compartment adapted for cooling the air that flows in from the return air opening portion; and an air supply device, disposed on the air supply opening portion, wherein, in the refrigerator, the exterior of the cooling compartment comprises: a separator, at least dividing a part of the supply air passage to form a space portion, the space portion being connected to the cooling compartment through the air supply opening portion; a freely controllable first opening portion, disposed in a separating region between the space portion and the divided supply air passage; and a freely controllable second opening portion, disposed in a separating region between the space portion and the return air passage or between the space portion and the cooling compartment.
