  • the present disclosure relates to a method of controlling a refrigerator including a heater for reducing dew condensation.
  • a refrigerator is a home appliance that can store foods in a refrigeration or freezing state using cool air generated through heat exchange with refrigerant that circulates in a refrigeration cycle.
  • a refrigerator compartment or a freezer compartment for receiving and storing the foods is provided inside a cabinet of the refrigerator.
  • the freezer compartment and the refrigerator compartment are selectively closed by a freezer compartment door and a refrigerator compartment door, respectively.
  • a heater is provided in provided in the cabinet and/or the refrigerator compartment door and the freezer compartment door to reduce dew condensation generated on surfaces thereof.
  • the heater heats a surface of the refrigerator compartment door and/or a surface of the freezer compartment door to reduce the dew condensation generated on the surface(s) of the freezer compartment door and/or the refrigerator compartment door by a difference between temperatures of the freezer compartment and the refrigerator compartment and an indoor temperature.
  • a heater in case of a previously set temperature condition, e.g., in case where an indoor temperature is higher than a previously set reference temperature, a heater operates in order to prevent a surface of a refrigerator compartment door and/or a surface of a freezer compartment door from forming dew condensation.
  • the heater since the heater operates without reference to the indoor temperature in case where it is difficult to form the dew condensation, power consumption of a product may unnecessarily increase.
  • US 2008/115514 A1 describes a refrigerator including a housing with an interior space defined by an exterior surface.
  • a heater is configured to heat a portion of the exterior surface.
  • a processor is configured to control the heater based on a dew point temperature outside the housing.
  • JP H10 339555 A describes a refrigerator. Detection signals of a casing surface temperature sensor and an outside air humidity sensor are inputted into a controller. A quantity of current applied to each dew preventive heater is computed based on these signals.
  • JP H10 332249 A describes a refrigerator having an outer air temperature sensor and an outer air humidity sensor. Detection signals from the outer air temperature sensor and the outer air humidity sensor are delivered to a control section and dew formation preventing heaters are supplied with required power.

  • a home bar 100 is installed in the refrigerator compartment door 30. Foods are taken in or out of the home bar 100 without opening the freezer compartment or the refrigerator compartment by opening the freezer compartment door 20 and the refrigerator compartment door 30.
  • the home bar 100 includes a home bar frame 110, a home bar door 120, a home bar housing 130, gaskets 140, 150 and a heater H.
  • the home bar frame 110 has an approximately rectangle frame shape.
  • a home bar opening 111 is defined in the home bar frame 110.
  • the home bar opening 111 serves as an inlet/outlet port through which the foods to be received in the home bar 100 are taken in or out.
  • a hook part 113 is provided in the home bar frame 110.
  • the circumference surface of the home bar frame 110 is divided equally in front and rear directions, and a rear end portion thereof protrudes inwardly to form the hook part 113.
  • the home bar door 120 has a shape corresponding to that of the home bar opening 111.

  • a circumference surface of the home bar door 120 including a circumference surface of the protrusion part 121 substantially faces the circumference surface of the home bar frame 110 including the a circumference surface of the hook part 113.
  • the back surface of the home bar door 120 except the protrusion part 121 faces a front surface of the hook part 113.
  • the front surface and the back surface of the home bar door 120 is flush with a front surface and a back surface of the refrigerator compartment door 30, respectively.

  • Another gasket 150 is provided on the backside of the home bar frame 110 adjacent to the home bar opening 111. At this time, the gasket 150 is extended to the home bar opening 111 from the backside of the home bar frame 110. Therefore, this gasket 150 is closely adhered to the backside of the home bar door 120, more specifically, to the backside of the projection part 121 of the home bar door 120, in a state where the home bar opening 111 is shielded by the home bar door 120.

  • the output of the heater H may be defined as 50% of the reference output P0.
