Definitions

  • Embodiments of the present invention relate to refrigerators, and more particularly, to control mechanisms for cool air circulation in refrigerators.
  • Refrigerators are electrical appliances capable of maintaining a storage chamber below the room temperature. Food can be stored in a refrigerator in a cold or frozen state.
  • the internal space of a refrigerator is maintained at a low temperature by circulating cool air therein. Cool air is generated through heat transfer of refrigerant through a cooling cycle including compression, condensation, expansion, and evaporation. Cool air supplied into the refrigerator is distributed or circulated in the internal space of the refrigerator to achieve a desired temperature.
  • a main body of the refrigerator has a rectangular parallel-piped structure with doors installed on a front side thereof.
  • a refrigerating space and a freezer are enclosed in the main body, each room having its own door.
  • a plurality of drawers, trays, and/or storage boxes may be installed in the refrigerator, e.g., for sorting the food or other items stored therein.
  • a top mount refrigerator has a freezer disposed above a refrigerating space.
  • a bottom-freezer refrigerator has a freezing space (or a freezer) disposed below a refrigerating space.
  • Bottom-freezer refrigerators have become increasingly popular. Usually users use the refrigerating space much more often than a freezer of a refrigerator.
  • a bottom-freezer refrigerator provides more convenience to the user because its refrigerating space is disposed in the upper portion of the refrigerator and the user can easily access the refrigerating space without bending or otherwise lowering the body.
  • the downside of such a refrigerator is that a user has to bend over the body when trying to get ice out of the freezer as the freezer is disposed at the lower portion of the refrigerator.
  • Embodiments of the present disclosure provide a refrigerator with an ice dispenser disposed on a door of a refrigerating space.
  • an ice machine for producing ice may be provided in the refrigerating space door or the refrigerating space.
  • cool air may need to be supplied from a freezer disposed below the refrigerating space to the ice machine installed in the refrigerating space. Therefore, there is a need for circulating cool air more efficiently to enhance power efficiency and ice-making performance of the refrigerator.
  • Embodiments of the present invention provide a refrigerator and a circulation control mechanism offering more efficient circulation of cool air in the refrigerator. Thereby the power efficiency and ice-making performance of the refrigerator can be enhanced.
